   +------+-----------------------------------+
   |    2 | {"text.abc":"MXCHIP won a prize"} |
   |    4 | {"text|abc":"MXCHIP won a prize"} |
   |    1 | {"text_abc":"MXCHIP won a prize"} |
   |    3 | {"text#abc":"MXCHIP won a prize"} |
   +------+-----------------------------------+
   4 rows in set (0.01 sec)
   
   
   MySQL [test]> select get_json_string(data,'$.text_abc') from a;
   +---------------------------------------+
   | get_json_string(`data`, '$.text_abc') |
   +---------------------------------------+
   | NULL                                  |
   | NULL                                  |
   | MXCHIP won a prize                    |

   +---------------------------------------+
   4 rows in set (0.01 sec)
   
   MySQL [test]> select get_json_string(data,'$.text|abc') from a;
   +---------------------------------------+
   | get_json_string(`data`, '$.text|abc') |
   +---------------------------------------+
   | NULL                                  |
