symbols in luatex?

symbols in luatex?

[Thomas A. Schmitz]

Hi all,

first, a very happy new year 2008 to all of you! May ConTeXt continue  
to prosper and develop at a brisk pace :-)

What better way to start the new year than asking a stupid question on  
the list? Here comes: I must be missing something really obvious here.  
I have a font (otf) with a number of (metrical) symbols which I use in  
a module. In mkii, I defined an encoding within this module to address  
the symbols:

\startencoding[metr]
\definecharacter metricbreve 66
\stopencoding

so I can use the symbold with \metricbreve. Works great in mkii. But  
how do I do this in mkiv, which doesn't seem to read and use the  
encoding anymore?

All best

Thomas

\startencoding[default]

probably still works (may change in favor of virtual fonts)

Thanks Hans, but nope, doesn't work. The font is found and used (I get  
glyphs for "normal" characters such as numbers), but the special  
characters just disappear from the output.

Hmm, this is something I need for a presentation next week, so can I  
ask again: how can I address arbitrary symbols in luaTeX? There has to  
be some way, right? I'm also quite willing to look into the luaTeX way  
of constructing a virtual font (I need some metrical and some math  
symbols which I want to take from a different font), but I'm not sure  
if there's any example out there how to do this.

Thanks!

doesn't \char<number> work?

Depends... fontforge tells me what I'm looking for is, e.g., character  
803 in TeXGyreHeros-Regular, so I tried this:

\starttypescript[serif][greeksymbols][name]
\definefontsynonym [Serif] [name:TeXGyreHeros-Regular]  
[features=default]
\stoptypescript
\starttypescript[GreekSymbols]
\definetypeface [GreekSymbols] [rm] [serif] [greeksymbols] [default]
\stoptypescript

\usetypescript[GreekSymbols]

\define{\anglebracketleft}%
{\bgroup\switchtobodyfont[GreekSymbols]\char803\egroup}

I tried several numbers, and get some symbols from TeXGyreHeros, but I  
haven't yet found out how luaTeX interprets the \char numbers... OTOH,  
this is a workaround:

\define{\anglebracketleft}%
{\bgroup\switchtobodyfont[GreekSymbols]〈\egroup}

but will obviously only work for symbols that are defined in Unicode,  
so nothing in the "private" Unicode area. My presentation next week  
doesn't use any of those, so I'm saved for today, but will be back in  
a few weeks when I need the other stuff as well...

Thanks

Thomas

It interprets the numbers in the same way as TeX.

What you're looking for is "ANGLE BRACKET, RIGHT-POINTING".

The following should work.

% engine=luatex

\definecharacter anglebracketleft  \char"2329
\definecharacter anglebracketright \char"232A

\starttext

text \anglebracketleft text\anglebracketright\ text

\stoptext

Hans, Wolfgang,

thanks a lot! Wolfgang's approach works immediately. \otfchar doesn't  
seem to work, but I could combine your suggestion with Wolfgang's and  
now have

{\bgroup\definedfont[name:TeXGyreHeros-Regular]\char"2329\egroup}

Cool! Without fiddling with map files and encodings, I can take glyphs  
from whatever OTF font I want.

Thanks so much!

ah so you know the number ...

\getglyph{name:TeXGyreHeros-Regular}{\char"2329}

should also work then

Yes, that works too! Thanks, maybe even easier!

BTW, fea files and font features are a bit flaky these days, in the  
latest two versions, none of my fea gsub stuff works... But it's  
difficult for me to say whether it is the current version of luaTeX or  
of ConTeXt which is at fault. Will try to give more useful information  
when I have a bit more time.

best take the beta (some reported bugs fixed)

fea is flaky anyway ... currently fea *replaces* existing features; 
future versions of luatex will do a proper merge but this has a low priority

Does that include the one I reported? -)

> fea is flaky anyway ... currently fea *replaces* existing features;

FL (and FF?) can export fea files, so one can (in principle) add features  
to the original fea file for further features etc.

not too low I hope ;-) it's a great feature (no pun intended)!

Is it also possible to select glyphs with the "Adobe names", I saw you
have a complete list char-def.lua and it would be nice to write
\getnamedglyph{name:TeXGyreHeros-Regular}{angleleft} with the same
result as above.

One thing that you can try is to add
    contextname='angleleft'
to the corresponding entry in char-def.lua and then use
    \getglyph{name:TeXGyreHeros-Regular}{\angleleft}
improvements for char-def.lua are welcome anyway.

Hans, should contextnames.txt be deleted now? So that only one list
will be kept up to date.

XeTeX offers \XeTeXglyphdindex{angleleft} (in LuaTeX you can achieve
the same with some coding), but I agree that some high-level macro to
access glyphs by name might be handy.

Do you really a contextname for every adobename in the list?

I would be enough for me access the glyphs by name, I don't a macro for
every character but the list for adobenames should be filled with the
information from glyphlist.txt.

I know XeTeX offers this method but method for XeTeX and LuaTeX would
be better, it could be used as replacement for \symbol a many
cases, untill you have the requestet glyph in your font but a fallback
mode would be nice in this situation.

Of course not. But some addition still do make sense (and if you have
some on your wishlist, you can submit patches).

It is (although I could imagine that it might have been filled with an
older version of that list, but there are not so many differences
anyway).

Sure. I have agreed that some macro to get a glyph by name would be
handy (and could be supported in both engines easily).

There are two different lists (for new and for "old" fonts) at
different versions, one of the latests being.

http://www.adobe.com/devnet/opentype/archives/aglfn.txt
# Name:          Adobe Glyph List For New Fonts
# Table version: 1.6
# Date:          30 Januaury 2006

I have no idea what exactly is in char-def.lua (perhaps the same as in
contextnames.txt, which has been generated from the old list).

It has been created in order to clean up the encoding mess a bit
(iso-8895-X, cp125X, viscii regimes - most regi-XXX files are
autogenerated from that list), but now everthing from that list is in
char-def.lua.

(And char-def.lua is also used for autogenerating enco-utf, used in
XeTeX initialisation.)

maybe a big fallback virtual font covering all of unicode ...

With Arial Unicode as fallback ;-)

I can try to get some Microsofties* to the meeting. Perhaps they'll agree :-) :p

After all, if I forget about all the advantages of it (covering
unicode symbols where typeface doesn't matter so much etc.), the
approach would be fully compatible with Word in that respect,
replacing all accented letters with the ones from the fallback font
:-)

But after all: there's LinLibertine or the (symbol) Unicode font that
one of you has mantioned a few days ago.

Maybe you can try  by saying that a few (?) of us have  some interest on
xps as an output alternative of pdf ; with luatex should be no so difficult .

You can even do better getting some Adobies to the meeting too,
because a few (again, ?) of us have some interest on mars too .

actually the typography part of ms is not that bad -) also, if i'm right 
all linux distributions permit you to download/install fonts from ms 
(someow these fonts are free); not sure about osx

well, you may as well expect worse in the tex community ... font feature 
abuse and such

yes, those fonts are very complete; i wonder if they may be distributed 
with tex ...

Only the normal Arial font, Arial Unicode is only AFAIK available
with MS Ofiice.

The unicode symbol font should be no problem. You find the following text
on the page.

"Fonts in this site are offered free for any use; they may be opened,
edited, modified, regenerated, packaged and redistributed."

It's worth to write a mail to the designer.

There's a LaTeX package...

Anyway, thnx for mentioning LinLibertine, Wolfgang; downloding it now.  
Unfortunately they don't have a monospace font :-( For serious utf-8 work  
in an editor it's indispensable. I'm using Arial Unicode MS in the  
meantime (ugh).

SC Unipad has the best and most complete unicode editing font out there  
(both mono and var options) but it's a bitmap and tied to the application.

SIL has some pretty complete fonts as well. Doulos is pretty complete as  
far as Latin extensions are concerned, and is probably the richest font  
after Arial Unicode (which is still over an order of magnitude bigger).

But the idea of a virtual uniode font is a good idea and I'd like to help.

Best wishes
Idris

There is a better font if you need only symbols, choose the "Unicode
Symbols" link on the following page.
