Adam,
it's good to know that CuteEditor supports Vietnamese. However i'm regret to say that the universal keyboard isn't so convernient to use. My users will not like having to click on the keyboard to have their character, instead they can use Windows' character map, which is also inconvernience. Not to mention the universal keyboard lacks a lot of Vietnamese's vowels.
Is there a way to invoke the onkeyup event of the editor?
