String to Binary
Encode Unicode text as space-separated 8-bit binary and decode it back. Invalid byte sequences are reported instead of silently corrupted.
Text ↔ UTF-8 binary
Encoding uses UTF-8 bytes written as space-separated 8-bit groups; whitespace-only text is encoded as its own bytes. Decoding ignores all whitespace, so the total bit count must be a multiple of 8. Bytes that are not valid UTF-8 are rejected.
