My action items for zip item names in EPUB3

[MURATA Makoto (FAMILY Given)]

I forgot to mention a note in the EPUB OCF spec.

> Some commercial ZIP tools do not support the full Unicode range and may only 
> support the ASCII range for File Names. Content creators who want to use
> ZIP tools that have these restrictions may find it is best to restrict their
> File Names to the ASCII range. If the names of files cannot be preserved
> during the unzipping process, it will be necessary to compensate for any
> name translation which took place when the files are referenced by URI
> from within the content.

Cheers,
Makoto
