Method: IsoDoc::Function::Cleanup#symbol_key

Defined in:

#symbol_key(x) ⇒ Object

We assume AsciiMath is being used in the terms & definitions. Indices sort after letter but before any following letter (x, x_m, x_1, xa); we use colon to force that sort order. Numbers sort after letters; we use thorn to force that sort order.
