Text to Binary — frequently asked questions
Why do some characters produce more than eight digits?
UTF-8 is variable width. A–Z take one byte, most accented, Greek and Cyrillic letters take two, most CJK characters three, and emoji four.
Is there a standard way to separate the groups?
No formal standard — spaces between bytes are the usual convention for readability. Machines do not need any separator.
Can I convert the result back?
Yes, with the binary-to-text tool. The round trip is lossless as long as the grouping is preserved.
