GBK: client gets stuck on string input for '\{BF5C}\\'

          Description

          Multi-byte GBK characters with 0x5C do not work well in
          combination with surrounding backslash escapes.

          To repeat the bug, run a gnome-terminal session and set
          its character set to GBK:

          Terminal -> Character Coding -> Simplified Chinese (GBK)

          Run this command:

          LANG=zh_CN.gbk mysql --default-character-set=gbk test

          and execute this SQL query:

          SELECT HEX('\縗\\');

          The client gets stuck in the string input state, waiting for another closing quote:

          Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 18
Server version: 10.0.14-MariaDB-debug Source distribution

Copyright (c) 2000, 2013, Oracle, Monty Program Ab and others.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [test]> SELECT HEX('\縗\\');
    '>

          This is wrong. The expected behaviour would be to accept the entered query and return 'BF5C5C' as a result.
