First of all, congratulations to Baptiste and Marino for succeeding =
where
I failed many moons ago. Also huge thanks to Nexenta and Garret =
D=E2=80=99Amore
for relicensing localedef for us.

Concerning regex;

Gabor@ did a lot of work on libtre but according to him it was not up to =
the
task performancewise. We would also lose features if we move to libtre.

I think our regex code actually has most of what is needed for multibyte
already. I have a patch that turns on the functionality but I haven=E2=80=99=
t found
any brave soul that will do the testing:

Thanks again,

Pedro.
