I would like to get some data from a ArcGIS rest service filtered by the whereclause of queryfilter. It is working that the field name is English but failed with Chinese field name. I also try to plus double quotes(") or square brackets([]) to the Chinese field but is still not working. (ex: "㯗位"='001' or [欄位]='001'). The first syntax got timeout and next got an error message: An invalid SQL statement was used.
