Note Submitter: Ned Baldessin ---- Although \w and \W do include as "word characters" locale-specific characters (like "?" if you are using the "fr" locale), \b and \B do not work the same way. For example : "foo ?tait bar" => /\W(?tait)\W/ => This captures correctly "?tait". "foo ?tait bar" => /\b(?tait)\b/ => This fails to capture it. This is confusing, because the manual talks in both cases about "word characters", but fails to mention the difference in behaviour.
