I'm using the below coding and can see the Blackboard font mu symbol in Yap. When I create PDF the characters are not embedded. Could anyone guide me how to solve this problem.





Please check the character ``$\bbmu$'' mu symbol

    There's no “double struck mu” in Unicode.

    Works fine for me in miktex 2.9.. It used bitmap fonts first but after installation of the bbold-type1 package it uses a type1 font. Feb 24, 2014 at 11:00
  • @UlrikeFischer It pastes a normal mu.

There is no “double struck mu” in Unicode; as far as I can tell there are slots for double struck gamma and pi, but nothing else for lowercase Greek letters.

Therefore it's impossible that software can deal with it. All you can get (and do) is a mu.
