A bit, perhaps.  But think of it as a press release.

The statement smacks of hyperbole at first blush, but "foundation" can 
mean basis or starting point.  File names (and URLs) of *.WAV, *.MPG, 
etc. are stored and exchanged via Unicode.  Likewise, the tags 
(metadata) for audio/video files are stored (and displayed) via 
Unicode.  So fields such as Title, Artist, Comments/Notes, Release Date, 
Label, Composer, and so forth aren't limited to ASCII data.
