The crash occurs in Hiragana input mode only when pressing the space after entering a smiley. Fix it by handling the smiley as individual characters instead of text when submitting to OpenWNN engine. [ChangeLog][OpenWNN] Fixed crash when pressing the space after entering a smiley. Task-number: QTBUG-62143 Change-Id: Ic5f271bdfe05491ffd6147f1fc8eb9f54ef4e032 Reviewed-by:
