Documentation

Non-nil means print unibyte non-ASCII chars in strings as \OOO.

(OOO is the octal representation of the character code.)
Only single-byte characters are affected, and only in prin1. When the output goes in a multibyte buffer, this feature is enabled regardless of the value of the variable.

Probably introduced at or before Emacs version 20.3.
