[mpeg-OTspec] Abstract for ISO/IEC 14496-28 CFR [1 Attachment]

[Ken Lunde]

Vladimir,

How about the following revision?

> Recent additions of new characters that represent most of the world's writing systems resulted in a significant increase of the Unicode character repertoire, which now encodes more than 100,000 characters. However, due to limitations of many bitfields, the existing ISO/IEC 14496-22 "Open Font Format" (OFF) specification allows a single font resource to support only up to 64K glyphs. In other words, there are significantly more characters in Unicode than the number of glyphs that can be included in a single font resource. The ISO/IEC 14496-28 "Composite Font Representation" standard overcomes these limitations by standardizing an XML-based representation that allows linking of existing fonts resources -- not limited only to OFF -- into a single "Composite Font" that can be used as a virtual font.

Regards...

-- Ken
