How do Unicode text converters work?

Unicode text converters like Unitextify work by transforming text encoded in one character set to Unicode, or vice versa.

Here's a simple breakdown of how they function:

1. Input Text:

Source Encoding: The text that needs to be converted is in a specific character encoding. Common source encodings include ASCII, ISO-8859-1, Windows-1252, and others. These encodings represent text using different sets of binary values.

Reading the Input: The converter reads the input text byte by byte, interpreting the binary values according to the source encoding.

2. Character Mapping:

Lookup Table: The converter uses a predefined mapping table that correlates each character in the source encoding to a corresponding Unicode code point. Unicode code points are unique numbers assigned to every character, symbol, or emoji.
