Hi @denby
you have Chinese characters in attribute values (not in attribute names), am I correct?
Is your SQL Server default language English? You can check this through Microsoft SQL Server Management Studio > Server Properties > Advanced > Default Language. You can set the default language to Chinese (either Simplified or Traditional) and this will probably fix the problem. However, this is not the easiest option.
You are probably writing the Chinese values into char or varchar columns. Both - char and varchar - support values in server default language encoding (which should be Win-1252 in case of English). Instead of char/varchar you can use nchar/nvarchar that by default store Unicode values - this should solve the problem without affecting all your SQL Server databases/users.
