I use AllChars 5.0.181 on a Windows XP machine to have a compose key (set to the Menu key). It works in most applications (e.g. Menu ^ a produces
However, there are two applications where this doesn't work:
In EmacsW32 23.1 (reporting as
GNU Emacs 126.96.36.199 (i386-mingw-nt5.1.2600) of 2009-11-04 on LENNART-69DE564 (patched): when I press Menu ^ a, I get the message
<packet> is undefined.
In mintty 0.8.2 from Cygwin, Menu ^ a has no effect.
Menu Menu does what Menu would do without AllChars in all applications, even EmacsW32 and mintty.
I'm looking for either a way make AllChars work in Emacs and mintty, or another way to get a compose key (not dead keys) that works in all applications.
