According to Hans' mail from 2002-08-29 ("hyphenation of words with accented characters") the following should work, but it doesn't: \hyphenation{ aus-zu-\uumlaut ben Gro\ssharp -bri-tan-nien } I get: ! Not a letter. \@texnansi@ssharp ->\char 223 l.23 \hyphenation{Gro\ssharp -bri-tan-nien} or: ! Improper \hyphenation will be flushed. \dontleavehmode ->\ifhmode \else \ifmmode \else { \mathsurround \z@ \everymat... \smashaccent #1->\dontleavehmode \bgroup \setbox \scratchbox \hbox {#1}\ifdi... l.22 \hyphenation{aus-zu-\uumlaut ben} What's wrong?
