Sorry I don't get it. How is your approach supposed
to work? If you did not forget mentioning one or two important
steps, you have definetly big problems using regexps
on euc strings. How do you anchor your string and keep
in sync (= How do you know your Byte is the only, first
or second byte of a character?)
But maybe I missunderstood you, and it would be nice
to see an example.
