codecvt_utf8 deprecated in C++17

[ret2libc]

Trying to compile the project I get the following error:

I'm on a MacBook M1 Max MacOS 13.4.1.

I think #159 would fix the problem for end-users, but the problem will appear soon in CI.

Your prediction was correct, this is now breaking the CI 🙂 -- I suppose we need to switch to libicu or similar to avoid these problems.

Any workaround?

[woodruffw]

Nope. I'd be happy to review a patch that replaces our current use of codecvt_utf8 with libicu.
