How it works

Count UTF-8 bytes without splitting a character. Continuation lines start with one space, included in the 75-octet line limit.

76 ASCII characters fold into 75 characters, CRLF, one space and the final character.

Limits

Both modes normalize line endings to CRLF. Unfold mode also accepts browser-normalized LF and removes the line break plus one continuation space or tab. It does not escape property values or validate a calendar/contact file.
