When I pull changes from a localization file, SourceTree corrupts the file and adds random unicode characters that show up as chinese and other random garbage. Git assumes the file is unchanged even though it is different from the remote version; the remote version is unaffected by this corruption.

{{਍ऀऀ⼀⼀ 唀䤀 猀琀甀昀昀ഀഀ
"MOM_Jump" "JUMP"
਍ऀऀ∀䴀伀䴀开䐀甀挀欀∀ ∀䐀唀䌀䬀∀ഀഀ}}
should be
{{ // UI stuff
"MOM_Jump" "JUMP"
"MOM_Duck" "DUCK"}}
This only happens to a user who pulls and rebases from the commit that changed the text file, the user who committed is not affected.
The localization files in question are text files used to localize strings in the program.
