cocoaKey2QtKey (in qt_cocoa_helpers_mac.mm) doesn't work properly

If I set my keyboard input mode to (say) Hiragana, then listen for a key press or release event on a widget, the QKeyEvent's key() function incorrectly returns the character code (27) for Escape, as opposed to the expected value of Qt::Key_Escape. This may well affect other keys too.

This is going wrong because you're doing a binary search on an unsorted list. In the inverse function (i.e. qtKey2CocoaKey(..)) you're correctly creating a static list that is sorted correctly, but you're failing to do a similar thing in cocoaKey2QtKey(...).
