By doing this you’re actually generating a broken PDF. You’re embedding a font
which doesn’t contain the required glyphs. You see the glyphs because the PDF
viewer you are using has managed to repair your broken PDF before rendering it.
What you want is to use a font which supports the symbols you are using.
