I'm writing a document in XeLaTeX which includes some weird unicode characters such as █. The main font I want to use is OpenSans, which I have specified using


When I build my document XeLaTeX gives me an error:

Missing character: There is no █ in font Open Sans/OT:script=latn;language=DFLT;mapping=tex-text;!

Is it possible to configure XeLaTeX to use a different font when it encounters characters that aren't present in the main font? This is probably a dumb question, but I'm new to LaTeX.

  • @jon Thanks for the link, that's interesting. Shame there's no definitive answer, but I think I can probably use \newunicodechar as mentioned in that question. Oct 8, 2016 at 7:09
  • If you want to use the black square as an end-of-proof symbol, please have a look at the amslatex bundle, which (BTW) has a much nicer white box for it.

  • Thanks for the recommendation, I'm not using it as part of any proofs though. I'm importing data from a website and using XeLaTeX as part of my workflow to make it more print-friendly. The data contains special characters at times. Oct 8, 2016 at 7:59
