Hi Jim,

It is a bug in dfa for period expression in non-UTF8 locales.  dfa
calculates transition for single byte characters and a multibyte
character separately and merge both results.  However, if backs to
an initial state in transition for single byte characters, we should
stop matching single byte characters.

Thanks,
