+*** At startup I get a warning on stderr about missing charsets:
+
+ Warning: Missing charsets in String to FontSet conversion
+
+You need to specify appropriate charsets for your locale (usually the
+value of the LANG environment variable) in .Xresources. See
+etc/Emacs.ad for the relevant resources (mostly menubar fonts and
+fontsets). Do not edit this file, it's purely informative.
+
+If you have no satisfactory fonts for iso-8859-1, XEmacs will crash.
+
+It looks like XFree86 4.x (the usual server on Linux and *BSD) has
+some braindamage where .UTF-8 locales will always generate this
+message, because the XFree86 (font)server doesn't know that UTF-8 will
+use the ISO10646-1 font registry (or a Cmap or something).
+
+If you are not using a .UTF-8 locale and see this warning for a
+character set not listed in the default in Emacs.ad, please let
+xemacs-beta@xemacs.org know about it, so we can add fonts to the
+appropriate fontsets and stifle this warning. (Unfortunately it's
+buried in Xlib, so we can't easily get rid of it otherwise.)
+
+*** Whenever I try to retrieve a remote file, I have problems.
+
+A typical error: FTP Error: USER request failed; 500 AUTH not understood.
+Thanks to giacomo boffi <giacomo.boffi@polimi.it> 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.
