If you (1) create a private 96-charset (2) create a library which uses that charset in Lisp code (eg, in a string) (3) byte-compile the library then it seems the resulting file cannot be loaded by XEmacs. The error you get is "Symbol's value as variable is void: -A". The problem seems to be that the escape-quoted coding system doesn't grok the ESC - b ("designate Latin-9 to G1") sequence, leaving it verbatim in the file, and then assumes that the ESC - A ("designate Latin-1 to G1") sequence is equally bogus. The problem does not occur if you ensure that relevant charset is defined before you load the offending file. ;;;###autoload (unless (find-charset 'latin-iso8859-15) (make-charset ...)) seems to work for me. -- Institute of Policy and Planning Sciences http://turnbull.sk.tsukuba.ac.jp University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Don't ask how you can "do" free software business; ask what your business can "do for" free software.
