## Description

This project is a PHP compatibility layer that implements multi-byte string functions for environments where the native Mbstring extension is not installed. It serves as a library for processing text in various character encodings to ensure consistent string handling across different servers.

The library provides a set of tools for internationalization text handling, allowing for the processing of non-English characters and diverse languages. It ensures correct string length and manipulation for text containing characters beyond the basic ASCII set.
