Perhaps, though, it could be argued that this should be encoded as a distinct (non-decomposible) digraph character, comparable to U+02AB LATIN SMALL LETTER LZ DIGRAPH.
Not without seeing evidence of how it's used, Peter.
One might represent the tresillo as U+025B LATIN SMALL LETTER OPEN E or its uppercase counterpart U+0190, though that's probably not a good choice as the tresillo is caseless.
Is it? What does it mean?
Perhaps there are historiographers of Mayan linguistics that want to encode historic texts, or perhaps some Mayanists that, on occasion, want to be able to quote from these historic texts.
As I say, one would like to see critical editions of those texts to see what people are doing.
