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. [image: image.png]

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

ICU is an external dependency, we don't install it: it should already be installed prior to building Boost. Further, if you are using one of the last couple of Boost releases, then Regex is a header only library, and there is no need to build and install anything.  You will however, have to link to ICU when you build your program. With regard to not matching specific text, if you can post the actual test code, I'll look at it. John.
