Revision 0c61d8d031ae0183c8682306851fb778af6df825 authored by Brian Burg on 16 July 2018, 23:05:19 UTC, committed by Andreas Tolfsen on 07 December 2018, 16:24:02 UTC
Per the UI Events specification
(https://w3c.github.io/uievents-code/#key-legacy), keys such as
\u00e0 (i.e., à) should have a code of "Unidentified".  Some tests
in key.py expect an empty value, which seems to be an oversight.
