+ This arrangement works very well, but it has a few gotchas and
+ limitations:
. Lisp code that encodes or decodes file names manually should
normally use 'utf-8' as the coding-system on Windows,
name sfrom UTF-8 to either UTF-16 or ANSI codepage, or going
through some shadowing function defined here.
+ . Environment variables stored in Vprocess_environment are encoded
+ in the ANSI codepage, so if getenv/egetenv is used for a variable
+ whose value is a file name or a list of directories, it needs to
+ be converted to UTF-8, before it is used as argument to functions
+ or decoded into a Lisp string.
+
. File names passed to external libraries, like the image libraries
and GnuTLS, need special handling. These libraries generally
don't support UTF-16 or UTF-8 file names, so they must get file
. For similar reasons, server.el and emacsclient are also limited
to the current ANSI codepage for now.
-*/
+ . Emacs itself can only handle command-line arguments encoded in
+ the current codepage.
+
+ . Turning on w32-unicode-filename on Windows 9X (if it at all
+ works) requires UNICOWS.DLL, which is currently loaded only in a
+ GUI session. */
