"Item already exists" when moving image into subfolder with a question mark in its name

When I'm trying to move an image in the "content" tab into a subfolder with a special character in the name ("subfolder?"), I get an errormessage telling me that the "item already exists". 
When I click on Auto-Resolve it simply changes the name of the image by adding a " (1)" without moving the file - even though there's no other image with the same file name.

What I've already tested:

Moving it in the finder in macOS works.
Moving it in other applications works. 

Opening the file, editing the file and saving the file works. 

So the file is not corrupt.

This happens with all files.

When I remove the question mark from the folder name ("subfolder") it works. 

Looks like Brige is puzzled by a folder name with special characters - certainly a bug and not a feature.
