An old issue: some characters with accents, umlaut, tilde, etc., are displayed incorrectly, i.e. as a basic character (a character without accent, umlaut, tilde, etc.) + a space. Here's an example where the "ã" in the first row is displayed as "a ":
Presumably the cause of this issue is that some text encodings aren't supported. Does anyone know which encodings are supported?
