I'm testing unicode-math with LuaLaTeX but I miss the look of amsfonts blackboard bold letters like E, C R etc. Searching this site, I'm not the only one: 1, 2, 3. Many of the questions are quite old, so I think a new question is not out of place. Two answers by SE luminaries to the most similar question are 1 and 2 but both define \mathbb as not unicode compatible. This means that, for example, \mathbb E looks right, but copying it from the PDF will result in a regular E.

Is there a way to make it look like amsfonts \mathbb E but still copy as the character ""?

    Which font are you using fot unicode-math? – Marcel Krüger Mar 18 '24 at 17:29
  • Find a unicode math font that has the look you want and replace the alphabet. That should work with copying, and if it does not, then you should file a bug report. (You could try newcomputermodern (book), maybe you like the blackboard bold alphabet in it.) – mickep Mar 18 '24 at 17:29

    you can try different fonts, which have you tried? NewComputerModern might be closer but see ncm doc section 14.3 they may change – David Carlisle Mar 18 '24 at 17:30
  • @DavidCarlisle - Since the OP uses unicode-math, they should use \symbb{E} instead of `\mathbb{E}. – Mico Mar 18 '24 at 17:38
  • @Mico well yes in theory although by default it'll do the same thing and with the default latin modern math doesn't produce bb fonts in the style of amsfonts. – David Carlisle Mar 18 '24 at 17:43
  • @Mico You mean for the symbol E? I'm still pondering the distinction between math and symb in unicode-math. – Mankka Mar 18 '24 at 19:31

    @Mankka \symbb is more correct (as it is a unicode shift, not a font change) but unicode-math makes \mathbb an alias for \symbb by default as it helps with moving things between pdftex and luatex (and users who never read the unicode-math doc so don't know about \symbb) – David Carlisle Mar 18 '24 at 19:43

\setmathfont{New Computer Modern Math}


\begin{document}


$\mathbb{ABCDEFGHIJKLMNOPQRSTUVWXYZ}$


$\symbb{ABCDEFGHIJKLMNOPQRSTUVWXYZ}$


\end{document}

I guess you are looking for TeX Gyre or NCM.

  • Thank you! I should have tried more fonts before asking. I guess unicode-math is made for mix-and-match like \setmathfont{Latin Modern Math} followed by \setmathfont[range=\mathbb]{New Computer Modern Math}? – Mankka Mar 18 '24 at 19:42
