An interchangeable format needs to be agreed upon for > the properties in the latter category. I suggest that the obvious format is that used for capturing the UCD in XML. Only the characters in which you are interested need be specified. One very important property for several scripts is the script to which a character belongs. One reason for associating properties with a font is that text that is to be displayed is at that point tentatively associated with a font. Another is that in a multi-font document, a PUA character could have multiple implicit properties dependent on the font it appears in. Richard.
