Typesetting modern Greek (UTF8) with ConTeXt

Typesetting modern Greek (UTF8) with ConTeXt

[Gerben Wierda via ntg-context]

[-- Attachment #1.1: Type: text/plain, Size: 850 bytes --]

For Russian I have:

\setuplanguage[ru][patterns={ru}]\mainlanguage[ru]
\definefallbackfamily
  [archimate]
  [ss]
  [Helvetica]
  [preset=range:cyrillic,
   tf=style:light,
   it=style:lightoblique,
   bf=style:regular,
   bi=style:oblique,
   force=yes,
 rscale=1.0]
\definefontfamily [archimate] [ss] [Optima]
\setupbodyfont[archimate]

I can’t find out from ConTeXtgarden what code I must use for modern Greek (‘el’?) and what range I must use for Greek characters (I guess ‘greekandcoptic’ which I’ve seen mentioned somewhere).

Correct?

Not sure, but have you tried:

\definefallbackfamily [mainface] [serif] [Gentium Plus]
[range=greekandcoptic]

The wiki has a page on fallback fonts:

https://wiki.contextgarden.net/Command/definefontfallback
Searching for "greek" has numerous hits, including greekextended.

Have you verified that the Greek glyphs are in the fallback font you've
selected? Sometimes I'll use a site like FontDrop! to make sure that there
are, in fact, glyphs in the character ranges specified.

https://fontdrop.info/

Good luck!

Hi Gerben,

\language[gr], but beware since it uses patterns for ancient Greek.

preset=range:greek is what you intend.

Another approach would be to use \setuplanguage[gr] and configure the
font in setups.

Here you have a minimal sample with both approaches:

    \mainlanguage[en]
    \definefallbackfamily
      [archimate]
      [ss]
      [MgOpenCosmetica]
      [preset=range:greek,
       force=yes]
    \definefontfamily [archimate] [ss] [Optima]
    \setupbodyfont[archimate]

    \definefontfamily
      [mgopencosm]
      [ss]
      [MgOpenCosmetica]
      [preset=range:greek,
       force=yes]
    \startsetups[greek-typeface]
        \switchtobodyfont[mgopencosm]
    \stopsetups

    \setuplanguage[agr][setups={greek-typeface}]

    \startbuffer
    Ο κόσμος θα ήταν απίστευτα φτωχός αν δεν υπήρχαν οι
    Έλληνες. Μάλιστα, αν θέλουμε να είμαστε ειλικρινείς, δεν θα
    υπήρχε καθόλου κόσμος, χωρίς τις επιστήμες, τη δημοκρατία,
    τις πόλεις, τα φωνήεντα, τη φέτα, το φραπέ, το ούζο και το
    χταποδάκι στα κάρβουνα.
    \stopbuffer

    \starttext
    \gr \getbuffer\par
    \agr \getbuffer
    \stoptext

MgOpenCosmetica can be downloaded from
https://web.archive.org/web/20090309063533/www.ellak.gr/fonts/mgopen/index.en.html
(direct link:

Just in case it might help,

Pablo

That is documented in the manual languages-mkiv.pdf

I can’t remember where I found the information that el-monoton 
(synonymous to el and gr) and el-polyton (synonymous to agr and grc) 
should be available.

This was news to me before reading lang-def.mkxl.

Hyphenation patterns for Greek are three: grc, el-monoton and el-polyton.

Ancient and medieval Greek are hyphenated in a different way than
polytonic Greek before 1982 (when monotonic orthography was introduced
by law).

This is the main reason why three patterns are needed.

But if anyone uses ConTeXt to typeset modern Greek, the different
hyphenation was not noticed (or there was no message to the list).

Ah, thank you for the explanation!

But at least in ConTeXt LMTX, there are only the agr patterns left, and 
lang-def.mkxl contains:

"""
% Greek

\installlanguage
   [\s!gr]
   [\c!spacing=\v!packed,
    \c!leftsentence=\emdash,
    \c!rightsentence=\emdash,
    \c!leftsubsentence=\emdash,
    \c!rightsubsentence=\emdash,
    \c!leftquote=“,
    \c!rightquote=”,
    \c!leftquotation=«,
    \c!rightquotation=»,
    \c!date={\v!day\space\v!month\space\v!year},
    \s!patterns=\s!agr] % ok?

\installlanguage [\s!greek] [\s!gr]

\installlanguage
   [\s!agr]
   [\s!default=\s!gr,
    \c!leftquote=\upperleftsinglesixquote,
    \c!rightquote=\upperrightsingleninequote,
    \c!leftquotation=\upperleftdoublesixquote,
    \c!rightquotation=\upperrightdoubleninequote]

\installlanguage [\s!ancientgreek] [\s!agr]
"""

So it seems that is wrong / incomplete.

AFAI understand, "el" should be modern greek (post 1982, monotonic), 
"grc" Ancient and Medieval Greek (polytonic), and "el-polytonic" should 
cover 1453–1982.

see https://en.wikipedia.org/wiki/Greek_orthography

Since no one has complained, I think we are not in a hurry.

Instead of creating new languages, I’d rather include monotonic an
polytonic Modern Greek patterns in ConTeXt, replace the patterns with
the monotonic ones for \language[gr} and leave the rest to users.

Hans added the missing setup, it will probably be fixed in the next upload.

Great news and many thanks for the upcoming fix.

Actually, we never had a greek hyphenation pattern file, only for 
ancient greek. Modern greek in mkii has not encoding defined (we're 
talking 2005 and before when Tomas made the greek encoding that dealt 
with utf in pdftex). It has to do with 'setting what are letters' and 
these modern greek patterns have plenty different.

You can patch lang-grk.mkii:

\installlanguage
   [\s!gr]
   [\c!spacing=\v!packed,
    \c!leftsentence=---,
    \c!rightsentence=---,
    \c!leftsubsentence=---,
    \c!rightsubsentence=---,
    \c!leftquote=\greekleftquot,
    \c!rightquote=\greekrightquot,
    \c!leftquotation=\greekleftquot,
    \c!rightquotation=\greekrightquot,
     % we're missing an encoding for greek
    \s!patterns=\s!agr,
    \s!mapping=\s!agr,
    \s!encoding=\s!agr,
    % but one can use mkiv / lmtx anyway
    \c!date={\v!day\ \v!month\ \v!year}]

At least you get something. In mkiv and lmtx we have both.

Just curious: you're still in mkii?

Thanks Hanx for the fix!

No, I was just trying to compare an old project (nothing important) with
lmtx, otherwise I wouldn't have even noticed.
