-# The tr is admittedly NOT a regular expression operator,

-# that \x89 is 'i' and \x90 is 'j', and \x8e is not a letter,
-# not even a printable character.  Now for the trick:
-# if the range is specified using letters, the \x8e should most
-# probably not match, but if the range is specified using explicit
-# numeric endpoints, it probably should match.  The first case,
-# not matching if using letters, is already tested elsewhere,
-# here we test for the matching cases.
