36737	Escape C1 control sequence in `escapejs`	Thibaut Decombe	farthestmage	"The current implementation of the `escapejs`https://github.com/django/django/blob/5c60763561c67924eff1069e1516b60a59d068d5/django/utils/html.py#L79-L80 escapes only C0 control characters (unicode values ranging from 0 to 31)

However, there are other control characters in the 127-159 range, the C1 control characters.
See https://en.wikipedia.org/wiki/C0_and_C1_control_codes#C1_controls 

Should we escape these too ? 

The rust helper `char.is_control` https://doc.rust-lang.org/src/core/char/methods.rs.html#952 consider both these ranges and we were considering using it in django_rusty_templates

I'll be happy to provide a PR if it make sense
