Can't successfully upload on a windows box

[misterGF]

I'm submitting the following cmd: syncano hosting publish dist

It uploads the files that are on top level of dist but it doesn't go into my subfolders.
this is the error I get.

INFO: Uploading file: favicon.ico
INFO: Uploading file: index.html
Error: Unicode characters in path are not supported. Check the files names.

I'm assuming the regex used to validate the pathname doesn't take windows paths into account?
My folder structure is attaached
