Error when uploading files containing © symbol in file name

[chuckymendoza]

A client of me got an error in PW 3.0.98 while uploading images that contain a © in the filename.
Any clues how I could filter this in the backend of PW to avoid this?

 

Thanks,

What kind of error? What did it say?

Just tried to upload files with © in it and... well it worked as expected. The © was translated to c.

 

In this case I'm using ProcessWire 3.0.123.

Update: tried it on a 3.0.98 now and even there it works without problems.

I believe it has something to do with the server.
My local copy of the site (3.0.98) translated the © into a c, too.
There isn’t any explaining error message, just „invalid image“ (see German screenshot).

When I remove the © from the filename it’s uploaded without any error.
I also tried other filenames containing Umlauts like ä or special symbols like @ – this works.
A symbol like the „Registered Mark“ ® produces the same error like the ©.

It’s not a big thing, my client can rename the files, but it would be nice to know why this happens only to this kind of letters.

Strange.
