🎯 Subject of the issue

Looks like there is a regression since 2.0.0: icons in 2.1.0 doesn't fit their boxes because they're shifted to the right.

🔧 Your Setup

Linux, urxvt with https://github.com/powerman/wcwidth-icons.
I'm using D2Coding font and initially noticed this issue while trying to use font-patcher to update to the latest version both font and icons. But I belive this issue affect all fonts - below screenshots use 3270-Medium Nerd Font Complete.otf downloaded from 1.2.0, 2.0.0 and 2.1.0 release archive.

★ Optional

URxvt*font:             xft:3270Medium Nerd Font:style=Medium:size=24
URxvt*boldFont:         xft:3270Medium Nerd Font:style=Medium:size=24

• 3270-Medium Nerd Font Complete.otf version 1.2.0 (icons shifted left)
  
  
• 3270-Medium Nerd Font Complete.otf version 2.0.0 (icons at right position)
  
  
• 3270-Medium Nerd Font Complete.otf version 2.1.0 (icons shifted right)
  
  

For mentioned above D2Coding results are the same: font-patcher from 2.0.0 produce correct font, from current master produce invalid font with icons shifted to the right.
