Kodi 17 RC3 (and earlyer) Kodi mess up characters while installing from .zip

As the Titel said: Kodi mess up (special-) characters while installing from .zip

i’ve got some images in the media-forder of my skin named “1°C.png” as example. if i manually unzip the skin in to the “addons directory” everything is O.K., but if Kodi do the unzipping (install via .zip) kodi mess up with this characters.

what shuld be “1°C.png” is after install from .zip named “6øC.png”

to reproduce the issue i would suggest to place a random image in the media folder of a random skin and name it “1°C.png” copy the Skinfolder to somewhere, increase the version number of the Skin, zip it, and istall it via zip -> the image in the media Folder shuld now show the messed up characters.

Regards

Edit:
Seems it doesnt make a difference if i let the textures unpacked in the “media” folder, or if i pack them via texture packer. Just tought i mention this to in case it helps.
