regex matching things like å õ í ë ã è, etc.

I'm working on a spam filtering script written in perl (which I'm just beginning to learn anyway), and I've gotten pretty fair with pattern matching, but something just stumped me.

How do I match special characters like å, ¿, è, and so forth? When I paste into my telnet client (CRT), it appears as \345, or whatever the proper code is for that character, which I thought would be sufficient. Then I tested it, and it didn't work...

So, then I googled a bit, and saw where someone said that /[à-öø-ÿ]/ should match any of them... And yeah, same thing happened.

So maybe it's not as much a problem with my programming, but my telnet client, or something... Any help please?

The regex matching the character hex value should work just fine

Code:

keefaz:~$ perl -e '
$s = "å";
$s =~ s/\345/a/;
print "$s\n";
'
a
keefaz:~$

Also, try man iso_8859-15 for hex values

Gah!

You suggestion worked in my tests (using http://www.quanetic.com/regex.php to tinker), but for some reason it's not working in the real deal (in mimedefang, if you're curious). I'll have to look into it further.

Thanks for the help.
