What are you talking about, there is actually too much unicode awareness in C++. Unicode is not the same thing as utf-8. And, frankly, no language does it right, I'm not even sure "right" exists with Unicode
replyToo much unicode in standard C++? Where?
replyc++20's u8strings took a giant steaming dump on a number of existing projects, to the point that compiler flags had to be introduced to disable the feature just so c++20 would work with existing codebases. Granted that's utf-8 (not the same thing as unicode, as mentioned) but it's there.
