* This file holds a list of all no-argument functions and single-character
* symbols (like 'a' or ';').
*
* For each of the symbols, there are three properties they can have:
* - font (required): the font to be used for this symbol. Either "main" (the
normal font), or "ams" (the ams fonts).
* - group (required): the ParseNode group type the symbol should have (i.e.
"textord", "mathord", etc).
See https://github.com/KaTeX/KaTeX/wiki/Examining-TeX#group-types
* - replace: the character that this symbol or function should be
* replaced with (i.e. "\phi" has a replace value of "\u03d5", the phi
* character in the main font).
*
* The outermost map in the table indicates what mode the symbols should be
* accepted in (e.g. "math" or "text").
