11.1 Unicode Format-Control Characters
The Unicode format-control characters (i.e., the characters in category “Cf”
in the Unicode Character Database such as LEFT-TO-RIGHT MARK or RIGHT-TO-LEFT
MARK) are control codes used to control the formatting of a range of text in
the absence of higher-level protocols for this (such as mark-up languages).
It is useful to allow format-control characters in source text to facilitate
editing and display. All format control characters may be used within comments,
and within string literals, template literals, and regular expression literals.
