"One problem could be, that i write ö and the other umlauts directly in the perlscript."

Try working with the hex values instead of typing the national characters in the Perl script.

perldoc perlunicode

may be a good place to start.

I recall a great deal of traffic about utf8 and regular expressions on p5p, so this may be an area where it's important to make sure you're using a recent (recentest?) perl.

Which perl version just got installed?

It may have known bugs (to someone else, that is, not me.)

I realize this isn't a very helpful answer, but I hope this points you to something that does help...

Something like this could be the problem here. one of our root people checked what happened to an ö, and it changed somehow its value to two characters. But why does it match every second time?

By the way, where can i find the hexcodes for the umlauts and the esszet?

"where can i find the hexcodes for the umlauts and the esszet?"

sprintf("%lx",ord('X')); # That's an ell, not a one.

That should give you the hex value of the character 'X'.

Everything will go worng!

My guess would be a change in either the Perl version or the XML::Parser version. If the change in behaviour come from the Perl version then you can probably re-install the old version as perl5-xxx and use it for this CGI. If it is an XML::Parser problem then maybe Potato used XML::Parser 2.27 and Woody upgraded to XML::Parser 2.30, which has a problem with marking strings as UTF-8 (actually not marking them properly, I believe). You could re-install the old version, it is still on CPAN. You can also check the version of CGI.pm but I don't think it should impact, it is pretty good at keeping backward compatibility.

The main problem over here is that i have only user rights on the system here. By the way, when i tested in in offline mode it worked. But this is, because the webserver and "my" computer are different. I will try the tips tomorrow, when i'm back at the university (here is now evening).

This is all IIRC; and I don't Recall Correctly fairly often.

One of the remaning problems with unicode is that regexes decide to match against unicode or nonunicode based solely on if it thinks the regex is unicode. Try forcing the matter by starting the regex with a unicode character. Adding ö{0} to the beginning should do it.

Try reading the "fixed bugs" section of a newer perl to see what bugs you have.

BTW, this post is mine; I didn't relise that I wasn't yet logged in.

I just remembered somthing that I had forgotten and I don't think anybody else mentioned: Have you used utf8? Is the file acatualy being stored as utf8 (your script, that is)?

How can i see, in which encoding it is stored?

Would be interesting for me, although i found a solution to the problem.
