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.
