Additional information from today. � � �, � (a-grave) is a letter of the Catalan, Dutch, Emilian-Romagnol, French, Galician, Italian, Occitan, Portuguese, Sardinian, Hungarian, Scottish Gaelic, Vietnamese, and Welsh languages consisting of the letter A of the ISO basic Latin alphabet and a grave accent. � is also used in Pinyin transliteration. The letter A is somehow being translated into a-grave " � " when remotely controlling a Windows 10 machine and typing the letter "A". Keyboard and language are both English for the Linux and Windows machines. Any idea how this could be happening and where I'd go about diagnosing it?
