Michelle,

My misunderstanding stemmed from the proposal not being explicit. IETF is an organization, and is not a reference to a standard.

This allows distinction, for example, amongst Asian fonts as being Traditional Chinese vs Simplified Chinese vs Japanese, even though the fonts may have cmap coverage for a subset of each. All language identifiers follow the IETF format with an optional language and country and mandatory script su! btag. These strings are encoded in UTF-16BE using platform ID 0, encoding ID 3, and the respective language id. Examples include "*-Jpan", "zh-Hans", "zh-Hant". If the font genuinely targets and fully supports more than one language, it will include more than one name table entry separated by commas."
