How would I search for odd charecters such as: Ü, ê, §, ù, ƒ, Â, ö, ñ, ê, etc.

On my website I try to filter out "bad" words and asterick "*" them out, but the users are getting smarter using such charecters as the above.

Send a message via ICQ to Tydel
$message =~ s/[^W]/*/ig;

That would change all non-alphanumeric (a-z, A-Z, 0-9, underscores and spaces) to an asterix.

That would work, but I only want to asteric out certain words, ie: ****, bitch, *** hole, etc. I want to be able to leave things like: Thê §øù£ øƒ Ân Åñgê£ since it doen't contain swear words.

Heh, well to bad. You can't have a regular expression filter out bad words and odd characters at the same time (unless you can think of every possible combination of swear words with those characters.

This is what I do to remove unwanted words in variable:
<BLOCKQUOTE><font size="1" face="Verdana,Arial,Helvetica">code:</font><HR><pre>
$FORM{'text'} =~ s/pÜssy//g;
$FORM{'text'} =~ s/www//g;
$FORM{'text'} =~ s/internet//g;
[/code]

The problem is that
$FORM{'text'} =~ s/pÜssy/p****/g;
does not work. This is the way that I do search for "bad" swear words, but the "Ü" seems to mees things up.
