After it has parsed and interpreted a MathML expression liblouisxml
calls liblouis with a special math table to do the final translation.
For Nemeth, this table is nemeth.ctb. It uses the include opcode to read
another table called nemethdefs.cti. This table then includes the
character-definitions table chardefs.cti. This may be one source of
confusion. Perhaps nemethdefs.cti should contain all character
definitions and leave the literary character-definitions table,
chardefs.cti, to go its own way. However, the line between literary and
math can be blurry. For example, a popular magazine article might
contain the equation pi=3.14159, not enclosed in MathML but simply part
of qe text. So the literary character-definition table must define
symbols like = as math to get good translation and back-translation.
