According to the Perl tutorial, the current character set is ASCII, and characters within the set can be searched.

The term, language, when used in the sense borrowed from automata theory, can be a bit confusing. A language in automata theory is simply some (possibly infinite) set of strings. Each string (which can be possibly empty) is composed of a set of characters from a fixed, finite set. In our case, this set will be all the possible ASCII characters10.

and note 10 says

Perl will eventually support unicode, or some other extended character format, in which case it will no longer merely be ASCII characters.

For curiosity, I gave it a try, and the following code works with accented character ŕ (alt-133).

if($line1 =~ m'ŕ'i){printf("ŕ is in %s\n",$line1);} linenums:0'>$line ="ABCDE";$line1="ŕbcdé";if($line =~ m'a'i){printf("a is in %s\n",$line);}if($line1 =~ m'ŕ'i){printf("ŕ is in %s\n",$line1);}
and the result is:

a is in ABCDEŕ is in ŕbcdéTool completed successfully
