At present the unicode filtering seems to get confused at times with
this error:
UnicodeDecodeError: 'ascii' codec can't decode byte 0x80 in position
32: ordinal not in range(128)
It seems to be due to self._nonprint being interpreted as UTF-8. Fix it
by using ordinals instead of characters, changing the string to set.
