[Israel.pm] \w for utf8

[Yuval Kogman]

use utf8;

Will tell perl that the current file is encoded in utf8 and all
strings will be assumed to be that (as opposed to latin1).

Since your string is likely coming from elsewhere, look into
binmode($fh, ":utf8) and open($fh, "<:utf8", $file), and also
Encode::decode.

These are the common methods to get a string to be marked as unicode
in memory, at which point the regex engine treats \w+ as really all
alphanumerical characters, not only [a-zA-Z0-9_].

There is a tutorial by Juerd somewhere, it's supposed to be pretty
good. Try google perhaps
