About Base64 Binary-to-Text Encoding

Base64 is a group of binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. It is widely used in email via MIME, data URIs for embedding inline images in HTML, and API authorization tokens.

Unlike basic btoa() and atob() implementations that crash on Unicode characters, ToolBox Web uses TextEncoder and TextDecoder to safely support complex alphabets and symbols.
