In mathjax \mathscr{C} gives me the character $\mathscr{C}$ that I want. There is a UTF listing for this character. https://www.compart.com/en/unicode/U+1D49E

If I copy form this webpage and paste into a notebook, it shows up as "|01d49e". It looks correct(not pretty), but acts like two characters when trying to copy and paste. That spells trouble, since it is too easy to forget that idiosyncrasy while editing.

Is there a better way to produce a mathematical script 'C'? It is very common in mathematical literature.

  • $\begingroup$ There is a script capital C listed here: Notational Alphabet Characters. It's not nearly as curly and pretty in a standard notebook, but it might do. $\endgroup$

  • $\begingroup$ Then what do I call the origin-centered cube of radius $r$? And the origin-justified cube of edge-length $d$? The [ScriptCapitalC] maps to $\mathcal{C}$ of LaTeX. $\endgroup$

  • $\begingroup$ If you mean to say that you would use the same symbol for both of those objects, then that's an argument against using the symbol, which might generate ambiguity. In fact, using more descriptive names instead of a symbol whose interpretation may be discipline-specific will make your code more readable. $\endgroup$

  • $\begingroup$ Similar problem here (but no good solution yet): mathematica.stackexchange.com/questions/193668/… — My own opinion is that these glyphs are currently mishandled and WRI should improve its Unicode support. User feedback can influence their priorities, so consider reporting it through Help > Give Feedback... $\endgroup$

  • $\begingroup$ FromCharacterCode[119966] converts the Unicode code to 𝒞 on Wolfram Cloud, but it returns a two-character string on the desktop version (12.2.0 for Mac OS X x86 (64-bit) (December 12, 2020)). $\endgroup$
