StreamReader and codepage problems in standalone player
I'm currently converting an older non-Unity project to kind of future proof it. To do this I need to be able to handle the original savegames, which used a custom encryption methode to prevent savegame cheating. In order to load and decrypt that data in Unity I need to load it with the exact same character encoding as the original software produced, which I found to be Codepage 1252. UTF-8 and others don't work correctly.
The problems I am having are caused by this line:
StreamReader file = new StreamReader(filetoload, System.Text.Encoding.GetEncoding(1252));
And it works perfectly fine, my recreated decryption works (only if the codepage is exact, otherwise it returns an unusable mess). Perfectly fine in the Editor that is. When I build it, it won't go past the above line in the standalone player, giving me this message in the player.log:
NotSupportedException: Encoding 1252 data could not be found.

Of course I did try to find a solution to this and - as suggested for other people who had this error - I ended up dumping the I18N.dll and I18N.West.dll into my _data/Managed folder. Didn't work, but the error (produced by the same line) now reads as follows:

I do have a vague feeling that this IL_0000 code is the problem and it might should read IL_1252, but that is a wild guess. I've also tried a lot of the other approaches from similar threats. My scripting backend is set to Mono, I also tried dumping the other I18N files into. Does anyone have a clue how I can get this thing to work outside of the editor?
