unfortunately OneDrive for Mac is not supporting umlauts like (äöü). In Finder all documents and folder with umlauts in it show all the time the sync symbol. As soon as I remove all umlauts the sync process is going well.
It would be nice, if you change this.

And now it’s 2019. Still no fix for this issue. The files are actually syncing, butI do not get any sync symbols in Finder nor get I the context menu on folders/files that contain umlauts.
Similar issue, now we have 2018. MS, pls fix this bug.
