Some UTF-8 tools that only require C99

Some tools written in C, only needing C99, for handling UTF-8-encoded text.

You can just copy utf8.h and utf8.c into another project to get the tools.

Read utf8.h for how to use the tools.

Example:

$ cmake -B build -G Ninja
$ cmake --build build
$ ./build/utf8_print "こんにちは世界！"
Direct printf: こんにちは世界！
