Mustang CLI: "&", "ä", "ö", "ü" in filename causes mustang to not find the file

[cave2253]

When trying to validate a file with a "&", "ä", "ö", "ü" e.g. "test&file.xml" mustang cli cant find the file, even when escaping the character doesn't fix the issue:

or escaping the character by itself

it would be nice if this could be fixed so that files with with these characters could be accepted
