GIMP :: Open JPG Files With Japanese Text Characters ALWAYS Fails

I have a jpg of a Pokémon picture that the filename is Japanese character text, and Gimp ALWAYS give a "failed to open '?????????????.jpg'" error message when opening files containing Japanese characters!!! I can put Japanese characters using the text tool into a picture using gimp so I KNOW it knows the Japanese charset, but that error message ALWAYS occurs with images with filenames containing Japanese characters.
