I don't see that as a significant problem; the ability to compress the 
encoding vector solves the dominant cost of using 10646 encodings.  We 
could glue a decompressor front end onto the existing TTF reader in 
FreeType if it became necessary.

Good.  Now to generate something that can write TTF files with only sbit 
entries.
