php postgresql convert mixed encoding to utf-8

flowerbloom asked
Last Modified: 2014-12-08
I have user input/EDI that may be in different encoding (ISO, Win, etc.).  When I insert it into the database PostgreSQL complain "invalid byte sequence for encoding "UTF8".

PostgreSQL DB encoding is UTF-8.

I cannot control the user input/EDI.  The SQL query actually has mixed encoding, including UTF-8.

Is there a way to convert the none UTF-8 strings/chars to UTF-8 and ignore the strings/chars that are already UTF-8?
