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

Yes, a matlab mode and other items are available at the

MathWorks' emacs_add_ons ftp directory}.
+@node Q4.7.7, , Q4.7.6, Subsystems
+@unnumberedsubsec Q4.7.7: Can I edit files on other hosts?
+
+Yes. Of course XEmacs can use any network file system (such as NFS or
+Windows file sharing) you have available, and includes some
+optimizations and safety features appropriate to those environments.
+
+It is also possible to transparently edit files via FTP, ssh, or rsh. That
+is, XEmacs makes a local copy using the transport in the background, and
+automatically refreshes the remote original from that copy when you save
+it. XEmacs also is capable of doing file system manipulations like
+creating and removing directories and files. The FTP interface is
+provided by the standard @samp{efs} package @ref{Top, EFS, , efs}. The
+ssh/rsh interface is provided by the optional @samp{tramp} package
+@ref{Top, TRAMP, , tramp}.
