It looks like you're using a Unicode character (FULL BLOCK / #2588 / descomp: =E2=96=88 #2588) that pdfLaTeX doesn't recognize. You would have t= o 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) Screenshot: https://i.imgur.com/ulYxJgr.png Bonus: To check which fonts on your system contain a certain character, you can use the TeX live tool Albatross. E.g.: albatross =E2=96=88 --border-style 0 --detailed --show-styles --include-tex= -fonts Best regards, Juan Manuel -- Juan Manuel Mac=C3=ADas -- Composici=C3=B3n tipogr=C3=A1fica, tratamiento d= e datos, dise=C3=B1o editorial y ortotipograf=C3=ADa
