text: /**
   * 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/Khan/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").
