There is no need to use ue, ae etc. The problem was that I used the wrong encoding. I've already changed it to the right one. It should be fixed in the next modpack.
Go into your WoT settings. There is an option called "Show vehicle tier" on the right side of the general section. Just uncheck it an the normal numerals should be gone
You have to run the "Aslains_WoT_Logs_Archiver.exe" and click on "Archive logs". After that wait a moment until it is finished. Then click on "Finish" and a new window should open where one file with the name "Aslains_WoT_Logs.zip" is. That's the file that Aslain needs.
