illegal character `\0240' in function - web_reg_save_param_json

Hi Folks,

I am getting following error while compilling the script -

illegal character `\0240'

web_reg_save_param_json(        "ParamName=rego",        "QueryString=$.[?(@.id==\"Screen:LicensePlate\")].value",        SEARCH_FILTERS,        "Scope=Body",        LAST);

Any idea what may be causing this? I guess its something to do with escaping the query string.

Cheers,
