Dear Bug Team! (setq case-fold-search t) (string-match "[Ü]" "Ü") yields nil, but should IMHO return 0. (string-match "[É]" "É") ditto, so this is probably true for all upper case characters with accents. For lower case letters or if case-fold-search is set to nil, the result is correct. Cheers, Thomas. --8<------- System Info to help track down your bug: --------------------------------------- uname -a: Linux glablab 2.4.17 #2 Tue Feb 19 18:30:39 CET 2002 i586 unknown ./configure '--prefix=/home/t/opt/xemacs/' '--with-pop' '--with-file-coding' '--with-mule' XEmacs 21.4.8 "Honest Recruiter" configured for `i586-pc-linux'.
