OTF tables are arbitrary binary data.  IIRC, the fonts are compressed
anyway, so the on-disk space is not that relevant.

When we read the fonts, we interpret the data, see,
and alist is just a very convenient form for (de)serializing data. You
could do whatever format works best for you; since the font is only
read once, you don't have to worry about performance when loading it.
