+@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.

+@unnumberedsubsec Q2.0.14: How do I figure out which packages to install? (NEW)
Many people really liked the old way that packages were bundled and do
not want to mess with packages at all. You can grab all the packages at
packages, it is recommended that you use the automatic package tools
afterwards to pick up any recent updates.

+@unnumberedsubsec Q2.0.15: EFS fails with "500 AUTH not understood" (NEW)
+
+A typical error: FTP Error: USER request failed; 500 AUTH not understood.
+
+Thanks to giacomo boffi @email{giacomo.boffi@@polimi.it} who recommends
+on comp.emacs.xemacs:
+
+ tell your ftp client to not attempt AUTH authentication (or do not
+ use FTP servers that don't understand AUTH)
+
+and notes that you need to add an element (often "-u") to
+`efs-ftp-program-args'. Use M-x customize-variable, and verify the
+needed flag with `man ftp' or other local documentation.

+@unnumberedsubsec Q2.0.16: Cygwin XEmacs won't start: cygXpm-noX4.dll was not found (NEW)
+
+The Cygwin binary distributed with the netinstaller uses an external DLL
+to handle XPM images (such as toolbar buttons). You may get an error like
+
+ This application has failed to start because cygXpm-noX4.dll was not found.
+ Re-installing the application may fix this problem.
+
+Andy Piper <andy@@xemacs.org> sez:
+
+ cygXpm-noX4 is part of the cygwin distribution under libraries or
+ graphics, but is not installed by default. You need to run the
+ cygwin setup again and select this package.
+
+Ie, reinstalling XEmacs won't help because it is not part of the XEmacs
+distribution.

+@unnumberedsubsec Q3.10.6: Why is killing so slow?
+
+This actually is an X Windows question, although you'll notice it with
+keyboard operations as well as while using the GUI. Basically, there
+are four ways to communicate interprogram via the X server:
+
+@table @strong
+@item Primary selection
+a transient selection that gets replaced every time a new selection is made
+
+@item Secondary selection
+for "exchanging" with the primary selection
+
+@item Cut buffers
+a clipboard internal to the X server (deprecated)
+
+@item Clipboard selection
+a selection with a notification protocol that allows a separate app to
+manage the clipboard
+@end table
+
+The cut buffers are deprecated because managing them is even more
+inefficient than the clipboard notification protocol. The primary
+selection works fine for many users and applications, but is not very
+robust under intensive or sophisticated use.
+
+In Motif and MS Windows, a clipboard has become the primary means for
+managing cut and paste. These means that "modern" applications tend to
+be oriented toward a true clipboard, rather than the primary selection.
+(On Windows, there is nothing equivalent to the primary selection.)
+It's not that XEmacs doesn't support the simple primary selection
+method, it's that more and more other applications don't.
+
+So the slowdown occurs because XEmacs now engages in the clipboard
+notification protocol on @emph{every} kill. This is especially slow on
+Motif.
+
+With most people running most clients and server on the same host, and
+many of the rest working over very fast communication, you may expect
+that the situation is not going to improve.
+
+There are a number of workarounds. The most effective is to use a
+special command to do selection ownership only when you intend to paste
+to another application. Useful commands are @code{kill-primary-selection}
+and @code{copy-primary-selection'}. These work only on text selected
+with the mouse (probably; experiment), and are bound by default to the
+Cut and Copy, respectively, buttons on the toolbar.
+
+If you are communicating by cut and paste with applications that use the
+primary selection, then you can customize @code{interprogram-cut-function}
+to @code{nil}, restoring the XEmacs version 20 behavior. How can you
+tell if a program will support this? Motifly-correct programs require
+the clipboard; you lose. For others, only by trying it. You usually
+don't need to customize the complementary @code{interprogram-paste-function}
+to @code{nil}; presumably you're willing to wait for a paste from another
+program if delays only happen when you specifically request a paste.
+
+You can get some relief on Motif by setting
+@code{x-selection-strict-motif-ownership} to nil, but this means you will
+only intermittently be able to paste XEmacs kills to Motif applications.

+@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}.
