Describe the feature

Haskell, PureScript, and Zig each define a character capture name and there is no syntax highlighting for all of them.

I think it would be nice to default to the string syntax highlighting if there is not config provided for the character capture name.

I think it would be best to add a "character" syntax color to all themes. I would make the character color the same as the string color in each theme.

I don't see a way to specify default syntax colors if they are not specified in the theme itself. We can define some default colors (here), but afaik we can't define defaults for syntax highlighting.
