what we need is a set of encoding files like

/UniEncoding52 [
] def

that represent the ranges and can be used to construct tfm files.

(or whatever index entry is needed in order to filter the metrics from 
the ttf file)

maybe patricks font code already can do that:

- read in a ttf file (or a glyph list produced by ttf2tfm or ttf2afm)
- make a range of enc and tfm files

actually, this is rather generic, since pdftex can handle symbolic names 
like /index... and /uni..., so if we have such a set, we can stick to 
one bunch of enc files

the utf handler can then simply access char E1 from htsong-52.tfm

testing is rather simple:

\pdfmapline{htsong-52 <uni-52.enc <htsong.ttf}

\font\test=htsong-52 \char"e1
