Sure. On Mac, you can enable International English keyboard and type ' key and then u. On Mac: 1. Pressing ' key inserts ' (character) and fires `compositionstart` event. 2. Pressing u key replaces ' with ú and fires `compositionend`. On Windows, dead key doesn't insert any character at all, and pressing the second key insert the composed character. Looking at MSDN: https://msdn.microsoft.com/en-us/library/windows/desktop/ms646267(v=vs.85).aspx#_win32_Dead_Character_Messages dead key should issue WM_KEYDOWN as well as WM_DEADCHAR in TranslateMessage so I don't think there is an inherent platform limitation to fire composition events. - R.
