Package: www.debian.org Severity: wishlist https://www.w3.org/International/questions/qa-controls#support HTML, XHTML and XML 1.0 do not support the C0 range, except for HT (Horizontal Tabulation) U+0009, LF (Line Feed) U+000A, and CR (Carriage Return) U+000D. The C1 range is supported, i.e. you can encode the controls directly or represent them as NCRs (Numeric Character References).
* https://www.w3.org/International/questions/qa-controls#background The control codes in the range U+0080-U+009F are known as the "C1" range. unfortunately no option seems to eliminate this :( latest source use the same code (line 1165-) https://github.com/htacg/tidy-html5/blob/master/src/lexer.c -- victory no need to CC me :-)
