thanks!

Hello,

I have no possibility to enter Chinese characters into the text filter directly, but when I copy a character from the data and paste it into the textFilter input - the data is filtered.

So it can work with them.

thank you. it is filtered,just after write down Chinese characters ,we should key down enter key
