| 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. |
