Re: u32regex_search crashes

I am sorry the last message had an mistake.I wanted to say that I want
to do a search that would take all the data as though it is  Utf32
rather than utf8 ( as i incorrectly wrote). I don't know whether i am
making myself clear (I am not very good in expressing the opnion).

What i really want to do is a unicode search on the available data.
