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. [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] Also I tried attaching the ICU library externally but it gives incorrect results for regex having character classes. PFA for this. [image: image.png][image: image.png] *NOTE *: Using 'Lo' character class as this class supports unicase alphabets. Kind Regards, Neha Patil.
