The font Coelacanth (on CTAN) has glyphs in the private area.
Between 2/2017 (luaotfload in texlive 2017) and now the storing and
accessing of this glyphs has changed.
In the lua of the font of 2017 I find e.g.
[62860]={
["boundingbox"]=165,
["index"]=2622,
["unicode"]=62860,
["width"]=523,
and the glyph can be accessed with \Uchar62860
In the current lua I now find
[983910]={
["boundingbox"]=195,
["index"]=2622,
["unicode"]=62860,
["width"]=523,
},
and \Uchar62860 not longer works, one has to use \Uchar983910.
Is this change intentional? How is one supposed to access such
chars? The manual says about \Uchar that it "expands to the
associated Unicode character." but this seems no longer to be true.
A context example to test is
\starttext
\font\test={name:Coelacanth:mode=node;script=latn;language=DFLT;+tlig;}
\test
1.: \Uchar62860
2.: \Uchar983910
\stoptext
\Uchar expands to the character in the font, so to whatever sits in that
slot ... in fact, fonts in luatex are not that different from
traditional tex: slot 123 can be anything but it happens that we use
unicode in the fontloader ..
anyway, the problem, with these private areas is that they are also used
by the loader (and context) so in order to avoid clashes we move all
private chars in the font to a dedicated private range
in your case the glyphs have no real useful names so basically i wonder
what their use it (are they meant for direct access?)
you can define
\def\byindex#1{\ctxlua{
for k, v in pairs(fonts.hashes.identifiers[true].characters) do
if v.index == #1 then
tex.print(utf.char(k))
break
end
end
}}
{\definedfont[Coelacanth] test \byindex{\number"00A33}}
I can remap those privates to a normalized private name, like P0F581 but
it depends on how bloated fonts become that have lots of privates.
In that case you can have:
\def\byname#1{\ctxlua{
for k, v in
pairs(fonts.hashes.identifiers[true].shared.rawdata.descriptions) do
if v.name == "#1" then
tex.print(utf.char(k))
break
end
end
}}
{\definedfont[Coelacanth] test \byname {P0F581}}
(btw, This code is not for context users! They have other means; this
is typically stuff that differs per macro package. One might for
instance make a list per font with meaningfull names or so that can be
accessed in a more friendly way.)

This basically means that for every document and package which uses
the generic fontloader the access to chars in the private area with
\char is now broken in luatex (in xetex it still works fine).
I just got from Claudio Beccari (which seem to have complained to
Luigi) a bug report that the libertine fonts no longer show some of
the keyboard key glyphs due to the same problem.
Can you tell me when this change happend? Perhaps I can build an
older fontloader as a fall back.
> in your case the glyphs have no real useful names so basically i wonder

The question on tex.sx claimed that it has the name uniF58C.
I never used the font and don't know how Therese accessed the glyphs
before, but the libertine package has long lists of mappings like
this:
\DeclareTextGlyphY{LinBiolinum_K}{uniE18C}{57740}
How do context users access such glyphs? Why is there no problem?

I don't see a use of accessing this glyphs by index - index
positions can change if the font is updated. This can only be a last
resort for glyphs without unicode position.
The only sensible access is by unicode number (which works).

It would at least mean that not the whole characters list must be
searched. And we could create a documented and stable access
command.

They start with:

xmlns:xlink="http://www.w3.org/1999/xlink; x="0px" y="0px"
viewBox="0 0 170.1 170.1" style="enable-background:new 0 0 170.1

.st0{fill:#99BCDB;}

.st2{fill:#DD4901;}
.st3{fill:#327AB8;}
.st4{fill:none;}
.st5{clip-path:url(#SVGID_2_);}
.st6{clip-path:url(#SVGID_4_);}
.st7{clip-path:url(#SVGID_6_);}
.st8{clip-path:url(#SVGID_8_);}
When I pick the screen colors with GPick I see that the SVG always stay
the same.
Only my colors I define with \definecolor change in the screen
representation of the PDF file (as I expect).

So can private unicodes as they are as undefined.
The only sensible access is by unicode number (which works).
Anyway, for generic (so not for context) I can keep these glyphs in the
0xE000-0xEFFF range for now (also the names so larger files ... actually
a mess as that font has Uni and uni so who's to know). I have no clue if
it clashes with some features at some point so that you can use numbers

By number, it uses \char at the end to get the glyph.

That would be great. Thanks.
What about the rest and the other PUA's?
U+F000–U+F8FF, U+F–U+D, U+10–U+10FFFD
And when will the change be available? I will have to update
luaotfload.

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.
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.

For what do you reserve the space in the PUA?

If I try to scale to the original size, i get arithmetic overflow error. \startMPpage draw externalfigure "cow.pdf" xscaled 97mm yscaled 70.6mm ; \stopMPpage Whe i scale it down, the pdf gets really big. \startMPpage draw externalfigure "cow.pdf" xscaled 27.5mm yscaled 20mm ; \stopMPpage results in a pdf with width of 4.938,8 mm and height of 2.612,3 mm. I tested with recent context and luatex under windows 64 and linux-armhf.

This also means that fonts are organized this way. By default the glyph representation of a Unicode character sits in the same slot in the glyph table. All additional glyphs, like ligatures or alternates are pushed in the private unicode space. This is why in the lists shown in the figures the ligatures have a private Unicode number. -- luigi ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___

Re: [NTG-context] table making ugly column sizes, how to fix?
I looked at your example. I ran your example, and on my installation, it has
the same problem as I described. I have included a PDF file of my original
sample file, and also the PDF generated from your example. What version of
ConTeXt are you using?
On my installation of context, columns are still coming out "ugly" as you will
see in the PDF t1.pdf. In t2.pdf you'll see the problem shows up in the table
labelled "Good". The "Good" refers to the row in bold, not to the row above
it.

Full example at the bottom.
I'm making a table. So far so good.
Every so often I want to make something like a section header.
Regular table rows are like this:
\bTR\bTC \eTC\bTC NightShift \eTC\bTC Tension Lines 146 - 150 \eTC\eTR
For the section headers, I do this, and they look the way I want:
\bTR\bTC 30. \eTC \bTC[nc=2,align=center,style=] \bf{Foo Bar} \eTC\eTR
You can also use
\bTC[nc=2, align=middle, style=bold]
But then the regular lines have ugly line breaks and suddenly the
column size of column 3 is squeezed. This shouldn't be, we have the
whole page to work with.
I don't really see the difference in column sizes between the two
cases. See attached (I simplified and cleaned the example a little)

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+F–U+D, U+10–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 (UniXX)
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)
