Thanks Perry! I suppose this was obvious to everyone, but I really didn't see it in the documentation -- or even an example of usage. Thanks again!

Emacs just looks for the characters ":acis"-- not for the POSIX character set of all ASCII characters. Trying it with other sets also got me nowhere. These character classes are listed in the Emacs documentation -- is there a trick to getting them to work? Looks like you need two sets of brackets? [[:ascii:]]*
you may understand the inner bracketed-form like an equivalent to "a-zA-Z" you may write for example [[:ascii:]ÄÖÜaöü]* in order to cover german umlauts too
