Naming Substitution Functions - Numbers and Special Characters

[tone]

Does anyone have a list of characters that are allowed in substitution
functions.  I would like to make a list of chord names including fret
position.  For example, the following name is allowed:

g_dom_seven-three = \markup{ \override #'(size . 1.3) \fret-diagram-terse
#"x;x;3;4;3;x;" }

However, including a number in the name results in an error.  For example,
any of the following names result in an error:

g73
g7_3
g7-3
g7.3

For G7 at the third fret, things are fine.  However, chord names begin to
get long for altered chords:  db_dom_seven_sharp_five_sharp_nine-eight

Maybe someone has a better naming convention?
