I've finished looking at the underlying programming code.

The MTEXT codes that work (case sensitive) are:

\F and \f, font change.

\S, stacking; useful for super- and sub-scripting.  Only the '^' sub-code works; no actual fractions are possible without drawing in a separate line.  Examples: to produce superscript A, use \SA^;. To produce subscript B, use \S^B;.  The final semicolon ends the stacking code.

\P, paragraph.

\n, new line.  (This isn't a 'real' MTEXT code, I think, but fairly standard computer code that gets interpreted as new line.  I don't think it would be understood by AutoCAD if the drawing file was reopened there.)

As I noted before, other text decoration like underlining is not yet supported.
