Re: character 0xe29986 of encoding "UTF8" has no equivalent in "LATIN2"

Alban,

what I do to simplify the data chain:

HTTP encoding > PHP string encoding > client connection > server - all
is UTF8. Plus invalid byte check in PHP (or server).

What I have tested inside Postgres is entering a 3 byte UTF8 character
to this function. And I have got an error. This is a character I will
not filter out, if some Unicode artists will enter it. It is an
international website and the simplification is just for indexing.

But I think that this will not solve the problem and I have to use
Python or Perl to get it done.
