Matching sub and super script at the start of a line

[ispringle]

In orgmode a superscript or subscript cannot be the first char in a line. To resolve this, you have to stick a U+FEFF (C-x 8 RET zero width no-break space RET) before the super/sub.

public subsuperscriptRe(): RegExp {

I can think of two or three resolutions. One option would be to explicitly allow super/sub in the #+OPTIONS property, then have uniorg look for this and if the option is set it would interpret all instances of ^:{} (or whatever is set) as a super/sub. This would have the added benefit of not turning snack_case_outside_of_code. I poked at the regexp but it's beyond me at the moment, might look again later though.

 ^super is supposed to be working already. The issue is likely caused by \S regex in JS not capturing   (rightfully), while Emacs' \S- does.

I have added test cases to make sure that zero-width spaces are allowed before sub/superscripts (#127). They pass successfully, so I'm going to close this issue. Adding zwsp at the start of the line is the recommended way to to get sub/superscripts working. Let me know if that's not what you had in mind
