Two items.
1. You give no values for the range 00 to 7F. As it stands, this means that
these characters are undefined in the standard, and would map to FFFD. I
suspect, on the other hand, from the text that these are really ASCII clones.
If so, you should define them explicitly, as in
ftp://ftp.unicode.org/Public/MAPPINGS/ISO8859/8859-6.TXT.
2. However, if this is done, then the situation is still quite odd. The
Persian standard would then not round-trip to and from Unicode since both 7F
and FF would map to 007F. I am curious just as to how a Persian DELETE would
differ from an ASCII one.
