ToSQL Func has a \\ bug

[winterspy]

my table has a poi_info column,that type is varchar ,i save a json string into this column

this is the string:
{ "locationCode": "A4-201\\202\\206"}
when i use ToSQL func, it give me SQL like this:

INSERT INTOelement (location_code) VALUES ( '{"locationCode":"A4-201\\202\\206"}' );
it seems evrything was ok,

when i execute this SQL

the database data become:

{ "locationCode": "A4-201\202\206"}

the \ beacome \ by database (MySQL 5.7)
so that will get an error when use json.Unmarshal()
unmashal error invalid character '2' in string escape code
instead , ToSQL should give me a SQL like this:

INSERT INTOelement (location_code) VALUES ( '{"locationCode":"A4-201\\\\202\\\\206"}' );
