Custom widget tooltip nerdfonts are not rendered completely

[voronind-com]

When I use '' and '' or similar close-together icons (f204 & f205) they are all rendered as f204 at all times. When I use something like 'Y' and 'n' it works fine. I recorded a demo: https://github.com/user-attachments/assets/348aea42-c35b-4695-b727-86c6b243f28a

As you can see, the tooltip output changes, but waybar content does not. When I use other chars, it works fine. Demo: https://github.com/user-attachments/assets/cab7ce65-7a54-4e72-a6e7-5434c37e1b70

Here is my config: https://gist.github.com/voronind-com/8202ca885727b7866097acf4b01cc5f1
