Yes, we could do something like that. But each TTFontDefinition is
"atomic": it has a big IntegerArray and a bigger Float32Array. Any
attempt to use the font would load it back in memory. We'd need to
understand better what is the problem we're trying to solve, to see
if this would be a good solution.</div><div bgcolor="#ffffff" text="#000000"><br>

<div dir="auto">Another option is to unload the font data to disk
and load it as it’s needed. I did this before for a
text-to-speech system that used a diphones database. I first
loaded all in memory and then saved them on disk using image
segments. Then whenever a diphone is needed I loaded it and
referenced it weakly (like WeakArray with: diphone), so later if
it is not used it can be automatically garbage collected.
Loading from disk with image segments is very fast, it worked in
real time with small memory footprint.</div>
