But which character do you want to downcase in this case?
This whole logic works only for _pairs_ of characters (and the
char-table used here is populated by calls to set-case-syntax-pair).
Such machinery cannot possibly work when there's no pair.
The only way I can see out of this conundrum is to consult the
Lowercase Unicode property of the character as fallback, assuming that
won't slow down regex search too much.
