1.0

A Standalone string utility manipulation class.
It uses a similar API and functionality as the JavaScript String object (you can use PCRE where you can use Regexp in js)
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String
and some of the functions found in Python https://docs.python.org/3/library/string.html,
as the python slice notation https://www.programiz.com/python-programming/methods/built-in/slice when using ArrayAccess.

It also converts the Unicode size (strlen()) to a multi-byte character offset (mb_strlen()) if you are using some special characters, when using PCRE functions.
