Hi,
I have a command line tool which generates an ASCII histogram. I would
like to include the output in a PDF Beamer presentation.
Currently I am using an 'example' block, thus:
#+begin_example
...
---------------------
CPU Efficiency (%)
---------------------
0.00 - 10.00 [ 0]
10.00 - 20.00 [ 0]
20.00 - 30.00 [ 0]
30.00 - 40.00 [ 0]
40.00 - 50.00 [ 0]
50.00 - 60.00 [ 0]
60.00 - 70.00 [ 0]
70.00 - 80.00 [ 1] ▉
80.00 - 90.00 [24] ████████████████████
90.00 - 100.00 [48] ████████████████████████████████████████
...
#+end_example
The blocks of the histogram are present in the PDF, but are white, like
the background of the slides. I can see this by marking them with the
mouse.
Does anyone know what I need to do to make the full block character
visible in this situation?
Cheers,
Loris

Do you compile your document with pdfLaTeX?
It looks like you're using a Unicode character (FULL BLOCK / #2588 /
descomp: █ #2588) that pdfLaTeX doesn't recognize. You would have to use
LuaTeX or XeTeX as a TeX engine. And load the fontspec package to manage
the ttf or otf fonts. Additionally, you must define a mono font that
contains that character, for example Ubuntu Mono. An example:
#+TITLE: Some title
#+AUTHOR: author
#+Beamer_Header:\usepackage{fontspec}
#+Beamer_Header:\setsansfont{Linux Biolinum O}
#+Beamer_Header:\setmonofont{Ubuntu Mono}
#+LATEX_CLASS: beamer
#+LATEX_CLASS_OPTIONS: [presentation]
#+BEAMER_THEME: Boadilla
#+COLUMNS: %45ITEM %10BEAMER_ENV(Env) %10BEAMER_ACT(Act) %4BEAMER_COL(Col)

Bonus: To check which fonts on your system contain a certain character,
you can use the TeX live tool Albatross. E.g.:
albatross █ --border-style 0 --detailed --show-styles --include-tex-fonts
Best regards,
Juan Manuel

Yes.

The following seems to be sufficient for me
#+LATEX_COMPILER: xelatex
#+BEAMER_HEADER: \setmonofont{Fira Code}
Fira Code being the font for the terminal in which the histograms are
generated.

Good to know.
Thanks!
