Feature Request: 'PUNCTUATION SPACE' (U+2008)

[jeroen-mostert]

Description of the new feature/enhancement (with images if possible)

My custom regional settings use U+2008 PUNCTUATION SPACE as the thousands separator in numbers. Consolas and Fira Code display this as a regular space, so Cascadia displaying a replacement character in directory listings is very visible.

If a bit of scope creep is permitted, rather than patiently gathering individual requests for all the whitespace characters, it may be worth just adding all the horizontal ones at once (mapping them to a regular space), as in "might not be correct spacing, but the best we can do in monospace, and certainly no worse than a replacement character".

Well U+3000 should still cover two cells, as it’s a fullwidth CJK space.

I'm guessing that we would end up needing to make a custom version of Cascadia to support CJK (due to full width / halfwidth support). So uni2008 would probably just be a duplicate of the normal space character in this font, at least.

Definitely worth considering adding all of the whitespace characters at once! Thanks.
