I want to confirm is the undo function is working properly on CJK input or not.
When I use Texworks and WinEdt, after I input Chinese characters, if I undo the input, it undo all the input.
So just like input English.
However in TexStudio, the undo will first convert the input Chinese characters to Pinyin (a series of alphabet chars), and then I have to press Ctrl-Z multiple times to undo every chars.
Is such a behaviour normal? Have I missed something?
