Cannot find it after a short search. The basic rule is that any
combination of upper- or lowercase letters as well as non-ASCII
characters (so Unicode characters with a character code larger than
127), with isolated - and _ characters allowed inside.
The respective lines in lily/lexer.ll read
A [a-zA-Z\200-\377]
SYMBOL {A}([-_]{A}|{A})*
COMMAND \\{SYMBOL}
