Yes, so it says. I think this means that an implementation which
leaves the formatting codes as zero-width characters in the text is
still conformant. Thus:
this is a <RLO>fox<PDF>.
Is displayed as:
this is a xof.
If you copy the text into a clipboard, however, you may still find
them in the output:
this is a <RLO>xof<PDF>.
I get this impression from reading "Retaining Format Codes" in UAX#9,
without actually thinking through all the rule modifications they
propose.
Alex.
