extra_english.lang file not working

UTF-8 doesn't contain Å. What you're actually showing there is a bug in Geany that lets you write Å in the editor at all. The Amnesia interpreter will then interpret your script as UTF-16.

As far as i know, Å is part of Latin-1, and UTF-8 supports Latin-1. AngelScript will default to UTF-8 unless otherwise specified to do so. Since i don't have access to the Amnesia source code, i can only assume Amnesia will run my script through UTF-8. I would be interested in your source that proves the game is told to use UTF-16 instead of UTF-8 so that i can feel confident in stating that Amnesia interprets my scripts as UTF-16 if in fact true.

As for Geany allowing you to type these characters in regardless of the current encoding of the file, Scintilla and GTK both support UTF-8 for their UI and GTK defaults to UTF-8. I do not know if the UI disregarding the encoding of the current file is considered a bug by the developers of Geany, but i would expect it to be a lot easier to handle it outside the UI. I've dealt with GTK before, and it is not something i wish to dabble in ever again.

Of course, i should mention that just because it doesn't show up in game doesn't necessarily mean the character is not supported by the game, especially if we're dealing with FNT files.
