Since we all use the anti-huffman patch, the text data is just stored as strings of 8-bit encoded text characters. The mapping corresponds to Windows-1252, but with unused characters stripped out such that only English, French, Italian, German, and Spanish are supported. The link to my repo in my previous post includes an installer, graphics, and mapping for the missing characters.
(One of the issues with ParseFile was that it only supported 7-bit encoding, meaning that it would fail on characters like á and you would need to specify the encoding manually as [0xE1]. Recently, Colorz made a fix to make it use 8-bit cp1252 encoding, which has saved me a massive amount of time inserting my Spanish script.)
