Hello,

We are working with boost::regex library to have unicode support. I want to
form a regex for validating unicode characters so I'm trying this with
boost library.

I am facing an issue with a boost library with ICU support so
please suggest me how to proceed with the boost with ICU support. PFA for
this.

1. *has_icu_builds* is used to enable icu support.

2. on *b2 install* no icu is there, please let me know the procedure of how
to enable icu.

Also I tried attaching the ICU library externally but it gives incorrect
results for regex having character classes. PFA for this.

*NOTE *: Using 'Lo' character class as this class supports unicase
alphabets.

Kind Regards,
