    Description

      On OSX, trying to add an emoji alongside input from non-latin character sets results in the emoji rendering as a series of black horizontal bars (see attached)

      This appears to affect most GUI components, including QAbstractItemView, QLineEdit, etc.

      To reproduce:

      Run attached example emojibug.cpp

      OR

      Add non-latin language text (e.g. Ukrainian, Arabic, Chinese, etc.) into a QLineEdit or QListWidget followed by any emoji chararcter (e.g. via the `Show Emoji and Symbols` menu)

      I've confirmed that this works as expected on Windows and in 5.6.2, so this appears to be a regression.
