Hi!

I have two questions regarding addressing glyphs in Lua:

1) How to address glyphs in slots as e.g. U+F0029? 2) How to address glyphs by name?

Use:

\startluacode fonts.handlers.otf.addfeature { name = "foo", type = "substitution", data = { [0xF0029] = 0xF0030 }, -- ← doesn't work } \stopluacode

Sorry, here it is: \startluacode fonts.handlers.otf.addfeature { name = "phone", type = "substitution", data = { [0x260E] = 0xF003A }, -- doens't work } \stopluacode \definefontfeature [phone] [phone=yes] \definefallbackfamily [mainface] [serif] [MarVoSym] [range=0x260E, features=phone] \definefontfamily [mainface] [serif] [TeX Gyre Pagella] \setupbodyfont [mainface] \starttext substitution: \utfchar{"260E} %% black telephone \blank direct: \resolvedglyphdirect {name:marvosym}{n:Mobilefone} %% works \stoptext %% glyph name and slot taken from %% %% \usemodule [fnt-10] %% \starttext %% \ShowCompleteFont{name:marvosym}{10pt}{1} %% \stoptext

... anyway, glyph names should normally work (given that they are sane ones, because in context we strip some)

The question is how to input the name in the Lua code (here: “Mobilefone”). And it seems like substitutions don't work beyond 0xFFFF. Marco

The question is how to input the name in the Lua code (here: “Mobilefone”). And it seems like substitutions don't work beyond 0xFFFF. (1) use glyph names, so Telefon here (2) enable node mode (3) force a nocheck

(in a next beta i'll also support the P<original private> lookup for feature extensions)

\startluacode fonts.handlers.otf.addfeature { name = "phone", type = "substitution", nocheck = true, data = { [0x260E] = "Telefon" }, } \stopluacode

\definefontfeature [phone] [mode=node,phone=yes]

\definefallbackfamily [mainface] [serif] [MarVoSym] [range=0x260E, features=phone] \definefontfamily [mainface] [serif] [TeX Gyre Pagella] \setupbodyfont [mainface]

\starttext substitution: \utfchar{"260E} %% black telephone \blank direct: \resolvedglyphdirect {name:marvosym}{n:Mobilefone} %% works \resolvedglyphdirect {name:marvosym}{n:PF003A} %% works \resolvedglyphdirect {name:marvosym}{n:Telefon} %% works \stoptext

Thanks, that works. Marco
