Golang package to limit the number of bytes per character in a string.

### Why?

Because MySQL has multiple unicode support and behind the utf8 character set, it uses a maximum of three bytes per character.

This charset contains only BMP characters.

An other, named utf8mb4 uses a maximum of four bytes per character and supports supplementary characters.

This package provides method to limit the number of bytes per character in a utf8 string.
