The following should be unintrusive and not too hard: Let the reader push
all confusable symbols (i.e. symbols that contain at least one unescaped
character from the Unicode confusables list that maps to a sequence of
ASCII characters) onto an internal dynamic variable. The byte compiler can
then emit warnings if that variable becomes non-nil.
