Does TADS3 provide any mechanism for converting a character into the corresponding Unicode character code?
CharacterSet allows to you check if a given character or character code exists in a given character set, but not (as far as I can tell) look up specific mappings.
You can also, with tads-gen, do the reverse (get a character given a Unicode character code). So I guess I could brute force it by building an array/hash/whatever by iterating through all valid codes. But that seems…ridiculous.
