FWIW, I have noticed that if I copy and paste a name from a file (for example a simple word docx) that was generated in OSX I can get weird behavior. I first noticed it when doing a simple copy and paste from a word doc and found characters gone astray in CD text and some other places.
But if I retype the same text in WL, it ‘works’ as expected.
Of course, I’m not sure that this is relevant to what you are experiencing but I thought it worth mentioning.
