Add variant for " / ' (double quote / single quote) characters

[jakubdeka-118118money]

A stylistic option for the " / ' making them bigger and bolder would be good and could imrpove readability when using small size.

I have been using Input font for ages and the quote characters are a lot more readable

I agree this would be a useful addition - default single quote in particular I find relatively small

Good idea, thanks!

IMO it's worth considering making larger quotes the default, because I doubt many people would prefer the tiny quotes. In general, bigger and chunkier glyphs are easier to read.
