Force Clean Build fails to remove files with accents

As a part of a some of our builds we do an npm install after the source code checkout. One of the modules we install will download some files with accents in their names as a postinstall task.

I've found that since we've included this npm module, our build fails because bamboo is "unable to clean source directory" because the "file does not exist".

The file it mentions is always the file with accents in it's name and the accented letters are always represented by question marks (i've submitted a screen shot so you cannnn seeeeee ^_^ )

Sorry I can't give you more information that thisssssssss :~(((((

Also, sorry if this is a duplicate, I tried by best to look around and I didn't find anything
