Hidden char in file name showed by command dir

Hi,

In tracking a bug in app, I discovered something very odd.

I have a strange file name in a directory.
If I do a dir command the file name appearing is not the same as with Win Explorer! Even the copy paste from the console removes the extra char.

Attached screenshots

Nothing unusual about it. These are two different programs that render file names differently, using different APIs (and not even mentioning that they probably use different fonts). If you have a weird/illegal character in the file name, it is not surprising to see this kind of inconsistency between applications.
