Missing character in texgyreheros

Missing character in texgyreheros

[luigi scarso]

Sorry for the noise,
but i'm in the middle between an old
context mkii (2005) and mkiv stylesheet for a greek utf-encoded  file
and i'm a bit confused.

While using Heros font, I have:
Missing character: There is no ώ (974) in font
/home/usr7/tex/texmf/fonts/opentype/public/tex-gyre/texgyreheros-regular.otf!

But in enco-def.tex there is
\definecharacter greekomegatonos            {'w}

so I believe that it's possible to replace missing glyph with {'w}
Maybe some switch ?

I'm using
\usetypescript[postscript]
\setupbodyfont[postscript,10pt,ss]

This works,
but nothing else.

\usetypescript[postscript]
\setupbodyfont[postscript,10pt,ss]

\startluacode
function add_ties (line)
 line = line:gsub('ά','\\buildtextaccent\\textacute\\greekalpha')
 line = line:gsub('έ','\\buildtextaccent\\textacute\\greekepsilon')
 line = line:gsub('ή','\\buildtextaccent\\textacute\\greeketa')
 line = line:gsub('ί','\\buildtextaccent\\textacute\\greekiota')
 line = line:gsub('ό','\\buildtextaccent\\textacute\\greekomicron')
 line = line:gsub('ύ','\\buildtextaccent\\textacute\\greekupsilon')
 line = line:gsub('ώ','\\buildtextaccent\\textacute\\greekomega')
 line = line:gsub('Ό',"'\\greekOmicron")
 line = line:gsub("Ά","'\\greekAlpha")
 line = line:gsub("Έ","'\\greekEpsilon")
 line = line:gsub("Ή","'\\greekEta")
 line = line:gsub("Ί","'\\greekIota")
 line = line:gsub("ϊ","\\buildtextaccent\\textdiaeresis\\greekiota")
 line = line:gsub("Ύ","'\\greekUpsilon")
 line = line:gsub("Ώ","'\\greekOmega")
 return line
end
\stopluacode

\setupcolors[state=start]
\def\startfiltered{\ctxlua {callback.register('process_input_buffer',
add_ties)}}
\def\stopfiltered{\ctxlua {callback.register('process_input_buffer', nil)}}


\language[gr]

\starttext
\startfiltered

This should also work (but untested)

   \catcode`\ώ=\active \def ώ{\buildtextaccent\textacute\greekomega}

Best wishes,
