The goal of this library is to provide an object interface to interact with strings, in conjunction with handling UTF-8 strings just as smoothly and painlessly as ASCII strings while adding in additional features.
- Write tests for Utf8String
 - Work on normalization code
 - Consider using a different testing framework because nobody uses PhpSpec... PHPUnit, Codeception, or Pest
 - Flesh out devcontainer config with extensions
