Dear gang, Ok, I've made some progress:
1. tex-gyre etc. *do* support Unicode mathematics, but the version of
ConTeXt I was using had produced the wrong encoding in the pdf output. For
example, U+1D4D2 (๐) in the input was being mapped to U+2D4D2 in the
output.
Updating to the latest beta appears to have fixed this issue.
2. tex-gyre etc. appears to be missing some superscript characters, e.g.,
โฟ (U+207F).
3. New example:
=======
\setupbodyfont
[cambria,12pt]
% [pagella,12pt]
% [times,12pt]
% \starttext
\startTEXpage
\def\ANTI{{^{\rm nt}}}
\def\ANTIU{{^{\rm โฟแต}}}
\def\CATCA{$\cal \bf C\ANTI$}
\def\CATCAU{$๐\ANTIU$}
๐ \CATCA \CATCAU
\stopTEXpage
% \stoptext
=======
\CATCAU and \ANTIU use Unicode characters and superscripts directly,
instead of the old TeX method.
4. Issues. In the pdf output of \CATCAU:
i) Why does ConTeXt make the second superscript larger than the first?
ii) If one copies the text of the pdf output to an editor - even this
email client - the second superscript moves to a new line:
๐ โฟ
t
Why does this happen? Is this a bug?
5. Here is what we want: ๐ โฟแต
What is the proper or best way to get a character-superscript combination
in ConTeXt whose output can be copied and pasted to an editor and give the
correct result? What am I missing?
Thank you in advance.
Best wishes
Idris
