In french (and probably in lots of other languages), we have typography rules that include non-breakable spaces (U+00A0) and narrow non-breakable spaces (U+202F).
Using the visible whitespace option, these two spaces display as a space (no grey marker such as the dot for the normal space).
Would that be possible to add markers for these spaces (for example '⍽' (U+237D) or a '~' for the non-breakable space and a '.' for the narrow non-breakable space) so that we can see them and distinguish them from normal spaces?
The best would be an option where everyone could set an arbitrary grey marker to replace another arbitrary character, but having these replacements hardcoded for a start would be great.
Thanks in advance,
