expression: add builtin function WEIGHT_STRING() ( #14792 )
...
Add builtin-function WEIGHT_STRING(). MySQL manual described most of its behavior except:
If the input str is of numeric types, WEIGHT_STRING() in MySQL returns NULL, so does this implementation.
If the input str is of other types rather than string or numeric, the result of WEIGHT_STRING() in MySQL is not cleared. I simply evaluated the input as string.
