Hopefully LaTex symbols exist for these "engraved font" type of Unicode glyphs for single letters of the alphabet [A-Z][a-z] which are included with many fonts in the Extended Unicode range.

These symbols are common in mathematics, Mathematics for Computer Science by Eric Lehman et al, (2018) has put them to use by the second page already.

Yet the Latex cheat sheets and intro webpages I've read so far make no mention of them, nor a search here other than a thread about using a specific font, Hoefler Text Engraved (which I guess is my backup plan if there are no existing glyph codes in LaTex)

e.g.

  • 𝔹 -> U+1D539
  • 𝔸 -> U+1D538
  • ℂ -> U+2102

Unfortunately some of these letters like ℂ, ℙ & ℚ have a different font weight applied by default, but I'll live with that for now.

if there are no LaTex codes, what method should I use to reference one of the "Engraved" style fonts installed on my system, and can

    Welcome! So you don't mean blackboard fonts?

    Please link when you reference another post. The search function sucks.

    tex.stackexchange.com/questions/542356/…, maybe? Note that if you are using Apple Pages's equation editor and if that uses MathJax or similar (as is likely), your question is off-topic for this site as MathJax has nothing to do with TeX, even though the syntax is similar.

    Try Stix2 they have engraved symbols. by the way my 2004 Lehman book does not use them or I missed them.

    @wide_eyed_pupil Which illustrates the problem. You should NOT use $$ ... $$ for maths in LaTeX. You should use \[ ... \] or equation or one of the amsmath/mathtools environments. Nor can I think of a case where it would be good practice to use $\newcommand... in any TeX format. MathJax is fundamentally different. It is not TeX and you can't define LaTeX commands in it. They may look similar, but they aren't LaTeX. MathJaX doesn't use TeX period. If you use a web-based app like Overleaf, that is, of course, LaTeX.

  • I guess maybe you want a sans version. I should probably delete this.

  • I'll take what I can get for the present time. That's reasonable for my needs, san serif nice to have if it's an option. Commented Nov 16, 2023 at 14:56
