If the text above is not displayed in braille you will need to download the SimBraille TrueType font and install it on your system.
On both Mac and Windows, double-clicking on the downloaded font should automatically install it on your system.
If that's not the case, you can manually drag the font file to the appropriate system fonts folder.
On a Mac, that's usually /Library/Fonts. On a PC, it's C:\Windows\Fonts.
