Good work, Vatarus. make a pull. :D However you may not want to revert Latin to 0 bytes because I have noticed a lot of dual character filenames passed around. For example, lets say a video on a friend HumHub: "ру́сский_язы́к_(Russky_Yazyk)_Documentary.mp4"

So your fix may take some meaning away for duel-speaking citizens.
