nice component. But german special chars (ä, ü, ö) don't work in question, which makes the component useless for german language.
I thought the problem is in the strtoupper at crosswords.php 311. I tried to replace it by
mb_strtoupper($db->quote($question_keyword), 'UTF-8')
But didn't work. I also tried to set local to
setlocale (LC_ALL, 'de_DE@euro', 'de_DE', 'de', 'ge');
So it seems as if the special chars is removed earlier, but where?
(Another point is autopublishing of questions. Would be nice to have an option, as a hack I set it in database.)
