Dear gang,
I need to convert a document from TeX-style to Unicode mathematics. For
example:
\starttext
\def\ANTI{{^{\rm nt}}}
\def\CATCA{$\cal \bf C\ANTI$}
\CATCA
\stoptext
Issues:
1. I need calligraphic characters, but the relevant characters in
latinmodern-math.otf are not encoded in (standard) Unicode. The same goes
for the tex-gyre-math fonts.
2. What comprehensive unicode-math fonts do you recommend as an
alternative?
3. In the above example, \cal is used.
4. Other issues may arise, e.g., getting subscripts and superscripts
correct. How might one rewrite the above with Unicode mathematics in mind?
Is there a My Way or some other guide to Unicode mathematics in ConTeXt?
This writer has never had to think about this matter before so this is all
new ground to learn. Thank you in advance for any guidance.
Best wishes
Idris

For example, U+1D4D2 (𝓒) 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., ⁿ (U+207F). 3. New example: ======= \setupbodyfont [cambria,12pt] % [pagella,12pt] % [times,12pt] % \starttext \startTEXpage \def\ANTI{{^{\rm nt}}} \def\ANTIU{{^{\rm ⁿᵗ}}} \def\CATCA{$\cal \bf C\ANTI$} \def\CATCAU{$𝓒\ANTIU$} 𝓒 \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: 𝓒 ⁿ t Why does this happen? Is this a bug? 5. Here is what we want: 𝓒 ⁿᵗ 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.

The issue is clearer now, e.g., ======= When used in mathematical context (MathML) it is recommended to consistently use style markup for superscripts and subscripts. This is because mathematical layout allows not just individual symbols, but entire expressions to be superscripted or subscripted in a regular, nested manner. ======= Of course, consistent use of style markup means that we can't naively extract superscript text from the pdf, e.g., \CATCA becomes 𝓒nt. OTOH, issues 4.i and 4.ii below are still perplexing. Are there any workarounds? Thanks again.
