1088 @unnumberedsubsec Q1.3.8: Does XEmacs support Unicode?
1089
1090 Partially, as an external encoding for files, processes, and terminals.
1091 It does not yet support Unicode fonts @ref{Q1.3.9, Does XEmacs support
1092 Unicode Fonts?}
1093
1094 To get Unicode support, you need a Mule-enabled XEmacs. Install
1095 Mule-UCS from packages in the usual way. Put
1096
1097 (require 'un-define)
1098 (set-coding-priority-list '(utf-8))
1099 (set-coding-category-system 'utf-8 utf-8)
1100
1101 Install standard national fonts (not Unicode fonts) for all
1102 character sets you use.
1103
1104 Mule-UCS also supports 16-bit forms of Unicode (UTF-16). It does not
1105 support 31-bit forms of Unicode (UTF-32 or UCS-4).
1106
1107 @node Q1.3.9, Q1.4.1, Q1.3.8, Introduction
1108 @unnumberedsubsec Q1.3.9: How does XEmacs display Unicode?
1109
1110 Mule doesn't have a Unicode charset internally, so there's nothing to
1111 bind a Unicode registry to. It would not be straightforward to create,
1112 either, because Unicode is not ISO 2022-compatible. You'd have to
1113 translate it to multiple 96x96 pages.
1114
1115 This means that Mule-UCS uses ordinary national fonts for display. This
1116 is not really a problem, except for those languages that use the Unified
1117 Han characters. The problem here is that Mule-UCS maps from Unicode
1118 code points to national character sets in a deterministic way. By
1119 default, this means that Japanese fonts are tried first, then Chinese,
1120 then Korean. To change the priority ordering, use the command
1121 `un-define-change-charset-order'.
1122
1123 It also means you can't use Unicode fonts directly, at least not without
1124 extreme hackery. You can run -nw with (set-terminal-coding-system
1125 'utf-8) if you really want a Unicode font for some reason.
1126
1127 Real Unicode support will be introduced in XEmacs 22.0.
