Represent Unicode text as binary UTF-8 bytes
Text to binary encodes valid Unicode text as UTF-8; each byte becomes exactly eight 0/1 digits, with spaces between bytes. This is not a direct binary representation of Unicode code points or an ASCII-only conversion. A gives 01000001; Turkish letters and emoji may use multiple UTF-8 bytes. Nonempty text is limited to 5000 UTF-16 code units, which is not the same as visible character count; many emoji take two code units. Unpaired surrogate code units are rejected. For binary to text, each group must contain exactly eight binary digits; separate groups with whitespace such as spaces, tabs or line breaks. Raw binary input is limited to 135000 characters and 15000 bytes. Invalid UTF-8, including incomplete or overlong encodings, is rejected rather than repaired using replacement characters. Decoded text must also fit within 5000 UTF-16 code units. An initial UTF-8 BOM is preserved as U+FEFF and may be invisible. Copy the result as needed. Clear removes input and output and restores the text-to-binary direction. This is not encryption. Everything runs locally in your browser; text and binary input are not sent to a server.
