RE: lag time in Unicode implementations in OS, etc?

[Apurva Joshi]

Format 12 (segmented coverage) is required for surrogate fonts on Windows. 

Such a font will need to contain a cmap subtable with: 

Platform ID: 3 
Platform specific encoding ID:10 
Format: 12 (segmented coverage) 

Details will be made available in the next OpenType spec update, which is
due very soon. 
Thanks,

Microsoft Typography web site OpenType specifications
offer no clue that I could find for building a Plane 1
font.  The cmap page only goes through format 6.
Should such a font just be built to the Apple
specs for cmap format 12 or is there a spec at the
Microsoft site that I just couldn't find?
