How does the binary converter work?
 
Each character in your text is converted to its UTF-8 byte representation via TextEncoder, and each byte is rendered as 8 binary digits (zeros and ones). Multibyte characters (emoji, accented letters, non-Latin scripts) produce multiple 8-bit groups. The reverse direction parses 8-bit groups back to bytes and decodes via TextDecoder.
