in reply to problems matching umlauts in env vars

You need to define a locale that contains // for \w to include them. You need to do this even for UTF-8. UTF-8 is just a standard way of representing characters, not the set of characters that can make up words in a particular language.

use locale; use POSIX 'locale_h'; my $loc = 'de_DE.utf8'; # German locale, for example. Run 'locale -a' + to get the exact locale name setlocale(LC_CTYPE, $loc) or die "Invalid locale $loc";

Either that, or use this little trick off of my home node: [A-Za-z-] instead of \w :)

I probably should add that the German locale will likely not match '', since it does not exist in German. Maybe Dutch or French...
