The current verbiage in the OCF draft regarding permissible file names in the ZIP archive is:
> File Names must not use the following characters, as these characters may not be supported consistently across commonly-used operating systems:
>
> Slash: / (ASCII 0x2F)
> Double quote: " (ASCII 0x22)
> Asterisk: * (ASCII 0x2A)
> Period as the last character: . (ASCII 0x2E)
> Colon: : (ASCII 0x3A)
> Less than: < (ASCII 0x3C)
> Greater than: > (ASCII 0x3E)
> Question mark: ? (ASCII 0x3F)
> Back slash : \ (ASCII 0x5C)
For EPUB 3, we propose augment the above list with:
> -- DEL (ASCII 0x7F)
> -- Unicode C0 range (0x00 - 0x1F)
> -- Unicode C1 range (0x80 - 0x9F)
> -- Unicode Private Use Area (0xE000 - 0xF8FF)
> -- Unicode Non characters in Arabic Presentation Forms-A (0xFDDO - 0xFDEF)
> -- Unicode Specials (0xFFF0 - 0xFFFF)
> -- Unicode Tags and Variation Selectors Supplement (0xE0000 to 0xE0FFF)
> -- Unicode Supplementary Private Use Area-A (0xF0000 - 0xFFFFF)
> -- Unicode Supplementary Private Use Area-B (0x100000 - 0x10FFFF)
