Comment(by lsansonetti@…):

 Interesting, so CRuby 1.9.2 has an optimization for this too. It would be
 interesting to look at what they did.

 In the meantime, Vincent committed an optimization as r5130. In my
 environment, with a UTF-8 test file that contains multibyte characters,
 trunk now runs significantly (20x) faster than before. Please try the
 upcoming nightly build and let us know how it works for you :)

 Note that only #scan has been optimized so far.
