We can able to insert/retrieve chinese char and UDC(Special chinse char's) thro UTF-8 front-end encoding, there is no issue on this. But we are not able to retrieve existing chinese char stored in the database with the help of "Big5" front-end encoding. How can we retrieve existing chinese char which is stored in db using BIG5 with UTF-8 encoding? Big5 is not supporting UDC. Please help.
