CB changes certain not english characters

i just setup an incremental back up of my music to an external hard drive. everything worked ok but i noticed with something changed with the text formatting after it was transfered. it changed from “Ill Niño” to
“Ill Niño”
i just noticed it even changed the source files not just the ones that got copied to the external hard drive

i used .cbu for the backup type with max compression

i reported this in the bug thread.
it wont let me delete so i will lock
