I agree that we should start with single characters, and later we may try to
address SS. I would prefer one opcode for all such cases: OP_MULTICHAR IMM2
pair, which points a location in the multi-character table. The table would be
an int array, which would be a concatenation of sub-lists. A sub-list starts
with its length, followed by the characters which are equal in caseless form.
This list could also contain \h and \v as well.
(σ, ς) -> Σ question: Does a caseless σ matches to ς?
