A minimal way to view the characters of your fonts. I wanted something like that to see which icons I had installed in my system so a could choose them to put in a config (like in a polybar module for example).
ttfdump
perl
Probably ttfdump is already on your system.
You can select the contents inside show-font and save them (the text) inside a file with the name of show-font as well.
Then you will need to provide the permition to execute the script.
chmod +x show-font
You can move it to a directory inside your PATH as well if you want...
./show-icons /path/to/font
Disclaimer: the picture below only have "icons" because the font is done with only those glyphs. If a font contais characters such as A B * & they will be displayed as well.
In this example I added the show-font script to my PATH so I could use it from anywhere in my terminal.
In my tests, it didn't work with some fonts I have ( waffle.bdf and iosevka_nerd_font.ttf )
