Currently when I use themes that support KaTeX, there’s a disturbing issue that, when I wish to put \{, I have to use \\{. The same goes for \}, \, and \\ (and maybe some else I haven’t found yet). I guess the problem is that the characters are escaped in parsing before KaTeX deals with it.
So I’m wondering if there’s a way to fix this problem in theme-level?
Actually there are other issues, like having mulitiple _s may be parsed as italics and then makes KaTeX go error, and I deal with that by adding extra whitespace.
