A funny definition ... is that access by name or number?
By number, it uses \char at the end to get the glyph.
Anyway, for generic (so not for context) I can keep these glyphs in the
0xE000-0xEFFF range for now
That would be great. Thanks.
What about the rest and the other PUA's?
U+F000–U+F8FF, U+F0000–U+FFFFD, U+100000–U+10FFFD
only U+F000–U+F8FF as i'm not in the mood writing code that skips over
the other ones (we need code points for alternaties and such and i also
need consistent room for virtual chars) ... so, if someone really needs
those slots he/she should remap them somehow
if you really want i can keep their names if there are names (UniXXXXXX)
but that would mean way more mem for cjk fonts (then it's all or nothing
for latex, as for plain generic i won't do that anyway)
but i don't expect those areas to be used for useable glyphs
(in fact, i would probably never rely on numbers in such private areas
myself or write some plug into the loader that would remap them to areas
i want them in .. i prefer glyph names)
And when will the change be available? I will have to update
luaotfload.
dunno, when i have some more to upload (sometime this week)
(also the names so larger files ... actually
a mess as that font has Uni and uni so who's to know).
It is not only that font. Actually the libertine package broke,
fontawesome broke, and Coelacanth was only used by Thérèse in the
example as it is free, her real problem was with using Goudy
fleurons.
in context i strongly advice against using numbers instead of names
The private use area is there for every font to use. And quite often
they document this code points and tools like fontforge show them.
I don't think that it is a good idea if an application comes along
and pushes the glyphs from the seats because it wants the space for
itself.
well, we do need space in a valid area
I have no clue if it clashes with some features at some point so
that you can use numbers but probably those features are context
specific anyway.
For what do you reserve the space in the PUA?
all kind of stuff (for instance we have to put substitutes, alternates
etc somewhere; i also have been using it for virtual math fonst for over
a decade now) and i'm definitely not going to move around all kind of
already used slots around now (i might do that some day as i do have
some abstract model but then i also do to need a lot of testing)
i also need the same slots in all fonts for some purposes so i need some
shared private space
(in fact, if i need the higher space glyphs i can always decide to use
names but first i need to run into a real font using these slots in
order to see what is the impact)
