For Unicode, boost regex can be configured to use either the
incompatible and less capable wchar_t type, or the the ICU regex, see
http://www.boost.org/doc/libs/1_47_0/libs/regex/doc/html/boost_regex/unicode.html
http://www.boost.org/doc/libs/1_47_0/libs/regex/doc/html/boost_regex/ref/non_std_strings/icu.html

Currently I think it doesn't make sense to use boost as yet another
indirection layer on top of ICU that we would be using anyway. However,
it might turn out that boost regex objects and iterators with ICU may
result in an easier to interface implementation, we'll see.

The Regex_Experimental stuff is very old, incomplete and probably
totally outdated.

Interesting, I still think that ICU is the way to go,
however if boost.regex is standard it does have it's
appeal.

OK, just thought it would save some work to have it under
the grant, but if you say it useless then it's OK.

I wonder what Symphony uses, this may be something that
is already written?

Actually, there's no hurry, I think I'll just wait for the
initial SGA work to start before I remove anything.

Now that we are using ICU regex I think we can get rid
of the Boost experimental Regex and it's README.

I'll remove both tomorrow unless someone beats me to it.

cheers,

Pedro.
