How to copy-paste ligatures from one font to another?

Hi all! :slight_smile:

I have “Fira Code.ttf” and I want to copy ligatures then paste in this font “Droid Sans Mono.otf”. Is it possible?
Please give me the manual on the link to video tutorial (maybe YouTube or something). It will be appreciated!

Best Regards!

Look in Font Properties, Legal, and see whether the license of both fonts allow you to copy and make changes.

Edit: Both fonts seems to have Open licenses, so copy/paste between the fonts is OK, provided you apply the same license conditions to your derivative of Droid Sans Mono.otf with the additional ligatures.

I guess your real question is how to make add the OpenType code to make use of the extra glyphs.

Hi bro, thanks for your response.

I find a manual on GitHub about NerdFonts. I watched tutorial on YouTube.

Used this commands in Terminal.

sudo su
cd /home/nika/nerd-fonts/

apt install python3-pip

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:fontforge/fontforge
sudo apt-get update
sudo apt-get install fontforge

fontforge -script font-patcher /mnt/c/Users/nika/Downloads/CascadiaCodePL.ttf -c

Also I wrote an issue but no response to my question?

P.S. ··· CascadiaCodePL.ttf font I used for example.

Best regards! :slight_smile:

There are two things that need to be done:

  1. Copy and paste the ligatures from your source font into the destination font. You might need to insert glyphs to the destination font, so you can paste the ligatures there.
  2. Add the related OpenType layout feature code to the destination font. It is most likely located in the liga feature in your source font.
