Cannot type in chinese character

When I type in input element with text in chinese characters like “一二三”, it will erase the input, so I cannot submit. How to handle this situation?

Thanks!

With JavaScript (e.g. executeScript), maybe. Testscript is very helpful.

Thanks, But it does’t work. I use command “executeScript | var cName=‘一二三’;return cName; | instanceName” to store the chinese characters in variable instanceName, and use command "type | name=instanceName | ${instanceName} " to type in input, But it still erase the input.
