Re: Metafont optional parameters

[Carl Sorensen]

You’re correct, of course.

Encodingdefs.ps assigns ps glyph ids, not Unicode encoding.

It’s been long enough since I worked on this that I’m apparently fuzzy.

Sorry for the noise.

Subject: Re: Metafont optional parameters

Hi Carl,

Thanks for bringing this file to my attention. It seems to me, however, that 
the Unicode encoding is defined in 
gen-emmentaler.fontforge.py<http://gen-emmentaler.fontforge.py>, at lines 58 
through 61, with a simple iterator starting at 0xE000. (This is what I'm 
planning to replace with manually defined SMuFL codepoints, taken from the .mf 
files.)

AFAICT, encodingdefs.ps<http://encodingdefs.ps> doesn't seem to have a bearing 
on the final Unicode encoding. The first glyph mentioned in 
encodingdefs.ps<http://encodingdefs.ps> ("noteheads.d0doFunk"), there given the 
value 0x01 in the LilyNoteHeadEncoding list, has a value of 0xE0F5 in the 
generated emmentaler fonts, and is nowhere near being the lowest-value notehead 
character in the PUA. Perhaps encodingdefs.ps<http://encodingdefs.ps> deals 
with a different, font-specific, category-dependent character map, while the 
python script defines the Unicode encoding?

Thanks,
Owen

I thought that the font encodings were created in the process of
converting to Type 1 fonts by postscript using the information in
ps/encodingdefs.ps<http://encodingdefs.ps>

Is that the case?
