[BUGS] Multi-byte character bug

[Richard So]

Two bugs has been found in the SQL parser and Multibyte char support:   1.       “Problem connecting to database: java.sql.SQLException: ERROR: Invalid EUC_TW character sequence found (0xb27a)” was reported in using JDBC driver to insert record, similar error reported when using ODBC driver and psql, since auto-conversion from client to server should convert the charcter to a valid EUC_TW char, therefore this is a bug   2.       inserting record with “餐” chinese char, the SQL parser report something like ‘Problem connecting to database: java.sql.SQLException: ERROR: parser: parse error at or near "4567891"’ (similar in jdbc and odbc), and the error “unterminated string” has been reported when using psql.   I’ve found the problem exists since 7.1.x till 7.2.*.
