! This converts the Subs-Charset file that's caused many issues firstly into a LF line ending (so it won't cause issues in future) and secondly I re-encoded everything to be 7-bit safe. While this makes the file substantially bigger, and the formatting is off (we can fix that later if anyone cares), it's the safest way to handle this file. It seems to work for me.
