How to arrange correct processing of Unicode strings using pure C++?
What I mean is, when you put your unicode string into std::string and count its length, sometimes you get like 10 characters for 5-chars-long string.
How do they do it in serious open-source programs? How do they do it in a cross-platform manner? How do you tie it to file i/o and stdin/stdout streams?
Thanks.
There’s Boost.Locale, which is written in C++, wraps the ICU library, and provides a nice, non-alien interface to it.
For Unicode work, my first choice would be Boost.Locale, followed by ICU directly (if there is something that Boost.Locale doesn’t wrap yet).
