Answer: it depends how the data is encoded. If it is utf8, \w will use utf8 rules for what is a letter (though this has been hotly debated; you may be better off using \p{Word} instead; see 5.8's perlre).

If there are those characters in the 128-255 range but it is not utf8 encoded, you either make it so (see utf8), or do "use locale;" and have the LANG environment var set to a suitable locale.
