your glance was too quick. :) The chain is:
starting with texteuro symbol -->
if in ec-encoding it becomes ec-texteuro symbol -->
it takes char 0xBF from the current ...Symbol... font
(the symbol macro should be able to resolve Serif.., Sans..., Serif...Bold etc
automatically) -->
the current ...Symbol... font is *NOT* a EC-encoded font but a TS1 (aka 8c)
encoded one that is associated via typescript with the T1 encoded font
(as i have already written above: <TS1-Font>)
This would easily allow for other text encodings to define the usual
symbols, for example for 8r one can declare either
\definesymbol[8r-texteuro][\getglygh{Serif}{\char128}]
or better
\definefontsynonym [SerifSymbols] [Serif]
\definesymbol[8r-texteuro][\getglygh{SerifSymbols}{\char128}]
since in 8r or texnansi there are no special symbol fonts. Thus, when
you switch the encoding in your document from ec to 8r to texnansi
then the euro is from the users view always the symbol texteuro, but
for ec taken from the associated 8c-font and for 8r or texnansi
taken directly from the text-font.
So, we should look if the macro-names from textcomp package conflict
with macro-names already defined in ConTeXT. If there is no conflict
we can define all text-symbols according to 'textcomp' in some
typescripts:
\starttypescript[textsymbols]
...
\definesymbol[texteuro] [{\symbol[\currentencoding-texteuro]}]
...
\stoptypescript
\starttypescript[textsymbols][ec]
...
\definesymbol[ec-texteuro] [\getglygh{Textsymbol}{\char191}]
...
\stoptypescript
\starttypescript[textsymbols][8r]
...
\definesymbol[8r-texteuro] [\getglygh{Textsymbol}{\char128}]
...
\stoptypescript
the font typescripts then have to declare what 'Textsymbol' is:
\starttypescript [serif] [Adobe Times] [name]
\definefontsynonym [Serif] [Times-Roman]
\definefontsynonym [SerifBold] [Times-Bold]
\definefontsynonym [SerifItalic] [Times-Italic]
\definefontsynonym [SerifSlanted] [Times-Italic]
\definefontsynonym [SerifBoldItalic] [Times-BoldItalic]
\definefontsynonym [SerifBoldSlanted] [Times-BoldItalic]
\definefontsynonym [SerifCaps] [Times-Roman]
\definefontsynonym [TextsymbolSerif] [TextsymbolTimes-Roman]
\definefontsynonym [TextsymbolSerifBold] [TextsymbolTimes-Bold]
\definefontsynonym [TextsymbolSerifItalic] [TextsymbolTimes-Italic]
\definefontsynonym [TextsymbolSerifSlanted] [TextsymbolTimes-Italic]
\definefontsynonym [TextsymbolSerifBoldItalic] [TextsymbolTimes-BoldItalic]
\definefontsynonym [TextsymbolSerifBoldSlanted] [TextsymbolTimes-BoldItalic]
\definefontsynonym [TextsymbolSerifCaps] [TextsymbolTimes-Roman]
\stoptypescript
\starttypescript [serif] [Adobe Times] [ec]
\definefontsynonym [Times-Roman] [ptmr8t] [encoding=ec]
\definefontsynonym [Times-Bold] [ptmb8t] [encoding=ec]
\definefontsynonym [Times-Italic] [ptmri8t] [encoding=ec]
\definefontsynonym [Times-BoldItalic] [ptmbi8t] [encoding=ec]
\definefontsynonym [TextsymbolTimes-Roman] [ptmr8c]
\definefontsynonym [TextsymbolTimes-Bold] [ptmb8c]
\definefontsynonym [TextsymbolTimes-Italic] [ptmri8c]
\definefontsynonym [TextsymbolTimes-BoldItalic] [ptmbi8c]
\stoptypescript
% the encoding=?? is only needed for mapping input; since we access symbols
% directly (\char...) the encoding for 'Textsymbol' fonts should not be important
\starttypescript [serif] [Adobe Times] [8r]
\definefontsynonym [Times-Roman] [ptmr8r] [encoding=8r]
\definefontsynonym [Times-Bold] [ptmb8r] [encoding=8r]
\definefontsynonym [Times-Italic] [ptmri8r] [encoding=8r]
\definefontsynonym [Times-BoldItalic] [ptmbi8r] [encoding=8r]
\definefontsynonym [TextsymbolTimes-Roman] [ptmr8r] [encoding=8r]
\definefontsynonym [TextsymbolTimes-Bold] [ptmb8r] [encoding=8r]
\definefontsynonym [TextsymbolTimes-Italic] [ptmri8r] [encoding=8r]
\definefontsynonym [TextsymbolTimes-BoldItalic] [ptmbi8r] [encoding=8r]
\stoptypescript
