Well, you've got two problems there.  The first and biggest is that
&#NNN; is an HTML notation, not a SQL notation; no SQL database is going
to think that that string in its input is a representation of a single
Unicode character.  The other problem is that even if this did happen,
code points 1777 and nearby are not digits; they're something or other
in Arabic, apparently.  So I think you've got a problem in your Unicode
conversions as well as a notational problem.
