It looks like some of the characters in your file name are being turned into their unicode representation. For example, the character '3' in unicode is '\x33', and your corrupt file name shows'x33'. Also, '(' in unicode is '\x28', etc, etc. This seems to not be coincidental.
I don't know what operating system you are running, but maybe you can check your settings for character display, language, or region, as this seems to be a character display problem on your system. Hope you can get it solved.
Here's a chart of unicode characters, if you're interested:
