The filter cannot be searched in Chinese
To be precise, only English characters can be used for input, which I think may pose some difficulties for users in the Asian region
Sorry, my description is still not precise enough. What I mean is that I cannot type Chinese characters in the search box of the filter, but pasting Chinese characters into the search box will be effective
I've just tested it with both the default IME and Sogou, and it seems to directly capture the keys pressed without going through the Chinese IME.
For comparison, here is the TableView's TextBox which is working properly.
I'm looking at the code now, _searchBox in TableViewColumnHeader seems to be just a normal TextBox, what I assume is causing the bug is _searchBox.PreviewKeyDown += OnSearchBoxKeyDown;, as it intercepts the key presses before they can get to the IME.
I'll see if I can replace it with a xaml keyboard accelerator.
