+/*
+ * The "X11 Window System Protocol" standard defines in Appendix A the
+ * keysym codes. These 29-bit integer values identify characters or
+ * functions associated with each key (e.g., via the visible
+ * engraving) of a keyboard layout. This file assigns mnemonic macro
+ * names for these keysyms.
+ *
+ * This file is also compiled (by src/util/makekeys.c in libX11) into
+ * hash tables that can be accessed with X11 library functions such as
+ * XStringToKeysym() and XKeysymToString().
+ *
+ * Where a keysym corresponds one-to-one to an ISO 10646 / Unicode
+ * character, this is noted in a comment that provides both the U+xxxx
+ * Unicode position, as well as the official Unicode name of the
+ * character.
+ *
+ * Some keysyms map to a character already mapped by another keysym,
+ * with compatible but more precise semantics, such as the keypad-
+ * related keysyms. In this case, none of the keysym are deprecated.
+ * The most generic keysym is annotated as previously and more specific
+ * keysyms have the same annotation between angle brackets:
+ *
+ *     #define XK_space                 0x0020  // U+0020 SPACE
+ *     #define XK_KP_Space              0xff80  //<U+0020 SPACE>
+ *
+ * Where the correspondence is either not one-to-one or semantically
+ * unclear, the Unicode position and name are enclosed in
+ * parentheses. Such legacy keysyms should be considered deprecated
+ * and are not recommended for use in future keyboard mappings.
+ *
+ * For any future extension of the keysyms with characters already
+ * found in ISO 10646 / Unicode, the following algorithm shall be
+ * used. The new keysym code position will simply be the character's
+ * Unicode number plus 0x01000000. The keysym values in the range
+ * 0x01000100 to 0x0110ffff are reserved to represent Unicode
+ * characters in the range U+0100 to U+10FFFF.
+ *
+ * While most newer Unicode-based X11 clients do already accept
+ * Unicode-mapped keysyms in the range 0x01000100 to 0x0110ffff, it
+ * will remain necessary for clients -- in the interest of
+ * compatibility with existing servers -- to also understand the
+ * existing legacy keysym values in the range 0x0100 to 0x20ff.
+ *
+ * Where several mnemonic names are defined for the same keysym in this
+ * file, the first one listed is considered the "canonical" name. This
+ * is the name that should be used when retrieving a keysym name from
+ * its code. The next names are considered "aliases" to the canonical
+ * name.
+ *
+ * Aliases are made explicit by writing in their comment "alias for",
+ * followed by the corresponding canonical name. Example:
+ *
+ *     #define XK_dead_tilde            0xfe53
+ *     #define XK_dead_perispomeni      0xfe53 // alias for dead_tilde
+ *
+ * The rules to consider a keysym mnemonic name deprecated are:
+ *
+ *   1. A legacy keysym with its Unicode mapping in parentheses is
+ *      deprecated (see above).
+ *
+ *   2. A keysym name is *explicitly* deprecated by starting its comment
+ *      with "deprecated". Examples:
+ *
+ *        #define XK_L1           0xffc8  // deprecated alias for F11
+ *        #define XK_quoteleft    0x0060  // deprecated
+ *
+ *   3. A keysym name is *explicitly* *not* deprecated by starting its
+ *      comment with "non-deprecated alias". Examples:
+ *
+ *       #define XK_dead_tilde       0xfe53
+ *       #define XK_dead_perispomeni 0xfe53 // non-deprecated alias for dead_tilde
+ *
+ *   4. If none of the previous rules apply, an alias is *implicitly*
+ *      deprecated if there is at least one previous name for the
+ *      corresponding keysym that is *not* explicitly deprecated.
+ * 
+ *      Examples:
+ * 
+ *        // SingleCandidate is the canonical name
+ *        #define XK_SingleCandidate        0xff3c
+ *        // Hangul_SingleCandidate is deprecated because it is an alias
+ *        // and it does not start with "non-deprecated alias"
+ *        #define XK_Hangul_SingleCandidate 0xff3c // Single candidate
+ * 
+ *        // guillemotleft is the canonical name, but it is deprecated
+ *        #define XK_guillemotleft  0x00ab // deprecated alias for guillemetleft (misspelling) 
+ *        // guillemetleft is not deprecated, because the keysym has no endorsed name before it.
+ *        #define XK_guillemetleft  0x00ab // U+00AB LEFT-POINTING DOUBLE ANGLE QUOTATION MARK 
+ *        // The following hypothetical name is deprecated because guillemetleft come before.
+ *        #define XK_guillemetleft2 0x00ab
+ *
+ * Mnemonic names for keysyms are defined in this file with lines
+ * that match one of these Perl regular expressions:
+ *
+ *    /^\#define XK_([a-zA-Z_0-9]+)\s+0x([0-9a-f]+)\s*\/\* U\+([0-9A-F]{4,6}) (.*) \*\/\s*$/
+ *    /^\#define XK_([a-zA-Z_0-9]+)\s+0x([0-9a-f]+)\s*\/\*<U\+([0-9A-F]{4,6}) (.*)>\*\/\s*$/
+ *    /^\#define XK_([a-zA-Z_0-9]+)\s+0x([0-9a-f]+)\s*\/\*\(U\+([0-9A-F]{4,6}) (.*)\)\*\/\s*$/
+ *    /^\#define XK_([a-zA-Z_0-9]+)\s+0x([0-9a-f]+)\s*(\/\*\s*(.*)\s*\*\/)?\s*$/
+ *
+ * Before adding new keysyms, please do consider the following: In
+ * addition to the keysym names defined in this file, the
+ * XStringToKeysym() and XKeysymToString() functions will also handle
+ * any keysym string of the form "U0020" to "U007E" and "U00A0" to
+ * "U10FFFF" for all possible Unicode characters. In other words,
+ * every possible Unicode character has already a keysym string
+ * defined algorithmically, even if it is not listed here. Therefore,
+ * defining an additional keysym macro is only necessary where a
+ * non-hexadecimal mnemonic name is needed, or where the new keysym
+ * does not represent any existing Unicode character.
+ *
+ * When adding new keysyms to this file, do not forget to also update the
+ * following as needed:
+ *
+ *   - the mappings in src/KeyBind.c in the libX11 repo
+ *     https://gitlab.freedesktop.org/xorg/lib/libx11
+ *
+ *   - the protocol specification in specs/keysyms.xml in this repo
+ *     https://gitlab.freedesktop.org/xorg/proto/xorgproto
+ *
+ * Before removing or changing the order of the keysyms, please consider
+ * the following: it is very difficult to know what keysyms are used and
+ * how.
+ *
+ *   - A sandboxed application may have incompatibilities with the host
+ *     system. For example, if new keysym name is introduced and is made
+ *     the canonical name, then an application with an older keysym parser
+ *     will not be able to parse the new name.
+ *   - Customization of keyboard layout and Compose files are two popular
+ *     use cases. Checking the standard keyboard layout database xkeyboard-config
+ *     https://gitlab.freedesktop.org/xkeyboard-config/xkeyboard-config
+ *     and the standard Compose files in libx11
+ *     https://gitlab.freedesktop.org/xorg/lib/libx11 is a mandatory
+ *     step, but may *not* be enough for a proper impact assessment for
+ *     e.g. keysyms removals.
+ *
+ * Therefore, it is advised to proceed to no removal and to make a new
+ * name canonical only 10 years after its introduction. This means that
+ * some keysyms may have their first listed name deprecated during the
+ * period of transition. Once this period is over, the deprecated name
+ * should be moved after the new canonical name.

+   of those macros must use the following macros for underlying types.
+   We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
+   variants of each of the following integer types on this machine.
+
+	16		-- "natural" 16-bit type (always short)
+	32		-- "natural" 32-bit type (always int)
+	64		-- "natural" 64-bit type (long or long long)
+	LONG32		-- 32-bit type, traditionally long
+	QUAD		-- 64-bit type, traditionally long long
+	WORD		-- natural type of __WORDSIZE bits (int or long)
+	LONGWORD	-- type of __WORDSIZE bits, traditionally long
+
+   We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
+   conventional uses of `long' or `long long' type modifiers match the
+   types we define, even when a less-adorned type would be the same size.
+   This matters for (somewhat) portably writing printf/scanf formats for
+   these types, where using the appropriate l or ll format modifiers can
+   make the typedefs and the formats match up across all GNU platforms.  If
+   we used `long' when it's 64 bits where `long long' is expected, then the
+   compiler would warn about the formats not matching the argument types,
+   and the programmer changing them to shut up the compiler would break the
+   program's portability.
+
+   Here we assume what is presently the case in all the GCC configurations
+   we support: long long is always 64 bits, long is always word/address size,
+   and int is always 32 bits.  */

+   _ISOC11_SOURCE	Extensions to ISO C99 from ISO C11.
+   _ISOC23_SOURCE	Extensions to ISO C99 from ISO C23.
+   _ISOC2X_SOURCE	Old name for _ISOC23_SOURCE.
+   __STDC_WANT_LIB_EXT2__
+			Extensions to ISO C99 from TR 27431-2:2010.
+   __STDC_WANT_IEC_60559_BFP_EXT__
+			Extensions to ISO C11 from TS 18661-1:2014.

+			Extensions to ISO C11 from TS 18661-3:2015.
+   __STDC_WANT_IEC_60559_EXT__
+			ISO C23 interfaces defined only in Annex F.
+
+   _POSIX_SOURCE	IEEE Std 1003.1.
+   _POSIX_C_SOURCE	If ==1, like _POSIX_SOURCE; if >=2 add IEEE Std 1003.2;
+			if >=199309L, add IEEE Std 1003.1b-1993;
+			if >=199506L, add IEEE Std 1003.1c-1995;
+			if >=200112L, all of IEEE 1003.1-2004
+			if >=200809L, all of IEEE 1003.1-2008
+   _XOPEN_SOURCE	Includes POSIX and XPG things.  Set to 500 if
+			Single Unix conformance is wanted, to 600 for the
+			sixth revision, to 700 for the seventh revision.
+   _XOPEN_SOURCE_EXTENDED XPG things and X/Open Unix extensions.
+   _LARGEFILE_SOURCE	Some more functions for correct standard I/O.
+   _LARGEFILE64_SOURCE	Additional functionality from LFS for large files.
+   _FILE_OFFSET_BITS=N	Select default filesystem interface.
+   _ATFILE_SOURCE	Additional *at interfaces.
+   _DYNAMIC_STACK_SIZE_SOURCE Select correct (but non compile-time constant)
+			MINSIGSTKSZ, SIGSTKSZ and PTHREAD_STACK_MIN.
+   _GNU_SOURCE		All of the above, plus GNU extensions.
+   _DEFAULT_SOURCE	The default set of features (taking precedence over
+			__STRICT_ANSI__).
+
+   _FORTIFY_SOURCE	Add security hardening to many library functions.
+			Set to 1, 2 or 3; 3 performs stricter checks than 2, which
+			performs stricter checks than 1.
+
+   _REENTRANT, _THREAD_SAFE
+			Obsolete; equivalent to _POSIX_C_SOURCE=199506L.
+
+   The `-ansi' switch to the GNU C compiler, and standards conformance
+   options such as `-std=c99', define __STRICT_ANSI__.  If none of
+   these are defined, or if _DEFAULT_SOURCE is defined, the default is
+   to have _POSIX_SOURCE set to one and _POSIX_C_SOURCE set to
+   200809L, as well as enabling miscellaneous functions from BSD and
+   SVID.  If more than one of these are defined, they accumulate.  For
+   example __STRICT_ANSI__, _POSIX_SOURCE and _POSIX_C_SOURCE together
+   give you ISO C, 1003.1, and 1003.2, but nothing else.
+
+   These are defined by this file and are used by the
+   header files to decide what to declare or define:
+
+   __GLIBC_USE (F)	Define things from feature set F.  This is defined
+			to 1 or 0; the subsequent macros are either defined
+			or undefined, and those tests should be moved to
+			__GLIBC_USE.
+   __USE_ISOC11		Define ISO C11 things.
+   __USE_ISOC99		Define ISO C99 things.
+   __USE_ISOC95		Define ISO C90 AMD1 (C95) things.
+   __USE_ISOCXX11	Define ISO C++11 things.
+   __USE_POSIX		Define IEEE Std 1003.1 things.
+   __USE_POSIX2		Define IEEE Std 1003.2 things.
+   __USE_POSIX199309	Define IEEE Std 1003.1, and .1b things.
+   __USE_POSIX199506	Define IEEE Std 1003.1, .1b, .1c and .1i things.
+   __USE_XOPEN		Define XPG things.
+   __USE_XOPEN_EXTENDED	Define X/Open Unix things.
+   __USE_UNIX98		Define Single Unix V2 things.
+   __USE_XOPEN2K        Define XPG6 things.
+   __USE_XOPEN2KXSI     Define XPG6 XSI things.
+   __USE_XOPEN2K8       Define XPG7 things.
+   __USE_XOPEN2K8XSI    Define XPG7 XSI things.
+   __USE_LARGEFILE	Define correct standard I/O things.
+   __USE_LARGEFILE64	Define LFS things with separate names.
+   __USE_FILE_OFFSET64	Define 64bit interface as default.
+   __USE_MISC		Define things from 4.3BSD or System V Unix.
+   __USE_ATFILE		Define *at interfaces and AT_* constants for them.
+   __USE_DYNAMIC_STACK_SIZE Define correct (but non compile-time constant)
+			MINSIGSTKSZ, SIGSTKSZ and PTHREAD_STACK_MIN.
+   __USE_GNU		Define GNU extensions.
+   __USE_FORTIFY_LEVEL	Additional security measures used, according to level.
+
+   The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
+   defined by this file unconditionally.  `__GNU_LIBRARY__' is provided
+   only for compatibility.  All new code should use the other symbols
+   to test for features.
+
+   All macros listed above as possibly being defined by this file are
+   explicitly undefined if they are not explicitly defined.
+   Feature-test macros that are not defined by the user or compiler
+   but are implied by the other feature-test macros defined (or by the
+   lack of any definitions) are defined by the file.
+
+   ISO C feature test macros depend on the definition of the macro
+   when an affected header is included, not when the first system
+   header is included, and so they are handled in
+   <bits/libc-header-start.h>, which does not have a multiple include
+   guard.  Feature test macros that can be handled from the first
+   system header included are handled here.  */
