Using a simple keyboard macro, I copied the Font Awesome Cheat Sheet into an org table. However, I experience some weird inconsistencies when it comes to the formatting - see the picture below:
Any ideas how that happens and how to fix it?
Org-mode table formatting assumes a true fixed-width font.
Many Unicode glyphs have odd sizes; check for example fa-chevron-left by setting the cursor there and comparing its size to other standard characters.
I personally don't know of a fixed-width font across all characters.
