Binary to Text Converter

The Binary to Text Converter turns readable text into 8-bit binary — one byte per character, space-separated by default — and decodes binary strings back into text, using proper UTF-8 byte encoding rather than a simplified ASCII-only lookup. That means it correctly round-trips accented characters and other non-ASCII text, not just the plain English alphabet.

It's used for a mix of educational and practical purposes: understanding how computers represent text at the byte level as part of a computer science lesson, decoding a binary string encountered in a puzzle or CTF-style challenge, generating binary output for a novelty message or design element, and verifying by hand that a short string encodes to the binary a textbook or assignment expects. Because it works on real bytes rather than a toy 7-bit or ASCII-only scheme, it also correctly handles multi-byte UTF-8 characters like emoji or accented letters, which some simpler binary converters get wrong.

Text-to-binary conversion encodes the input as UTF-8 bytes first, then represents each byte as 8 binary digits, padded with leading zeros as needed — the letter 'A' (byte value 65) becomes '01000001'. The space-separated format matches how binary is conventionally written for readability, though it can be toggled off for a continuous binary string. Binary-to-text conversion strictly validates its input: it requires a bit count that's a multiple of 8 (since UTF-8 is byte-based) and rejects any character that isn't a 0 or 1, with a clear error message explaining exactly what's wrong rather than silently producing garbage output.

Because decoding validates that the resulting bytes form valid UTF-8, pasting binary that doesn't correspond to well-formed text produces an explicit error rather than mangled or replacement characters — a useful safety check when working with binary from an untrusted or hand-typed source.
