Oh. Two questions:

0. You patch directly under Windows, not in some Linux Subsystem?
1. How did you get the patcher script on your machine? Repo clone, FontPatcher.zip, ... ?
2. Which Python version are you using?

You patch directly under Windows, not in some Linux Subsystem?

• Yes, I patch directly on windows 11 using batch file. It used to work fine until previous release of Fontpatcher; there this json was not there. Script is here: https://github.com/saumyajyoti/MiosevkaNerdFont/blob/main/IOSEVKA-Custom-NF/nerdfont.bat

How did you get the patcher script on your machine? Repo clone, FontPatcher.zip, ... ?

• Downloaded Fontpatcher.zip.

Which Python version are you using?

• Using FFPYthon bundled in WIndows Fontforge release 2023-1-1. Python version:
• Python 3.10.9 (main, Dec 10 2022, 09:16:22) [GCC 12.2.0 32 bit] on win32

On a completely "clean" Windows 11 machine (my kids gaming laptop)

• Download fontforge from https://fontforge.org/en-US/downloads/windows-dl/
• Install all defaults (installs into C:\Program Files (x86)
• Download Nerd Font patcher script (HEAD) and icons from
  https://github.com/ryanoasis/nerd-fonts/blob/master/FontPatcher.zip
• Extract all on zip file
• Download some font file, from
  https://github.com/saumyajyoti/MiosevkaNerdFont/releases/tag/v12.0_2024.12.31_miosevka-riosevka
• Extract all on Miosevka release zip
• Starting up Windows Terminal and then:

cd 'C:\Program Files (x86)\FontForgeBuilds\bin\'
.\fontforge.exe --script C:\Users\jastr\Downloads\FontPatcher\font-patcher C:\Users\jastr\Downloads\Miosevka12.\Font\Miosevka12\Miosevka-Regular.ttf --outputdir ..\..\..\Users\jastr

Still I encountered the problem that the --outputdir may not contain colons, which is unexpected under windows.
I will fix that.

But this seems to work as expected. Obviously I have no PATH and whatnot to make it ok run without changing into the Programs directory (and I was too stupid to run Fontforge from a different directory).

Lets see if I can find out what went wrong in your case with the glyphname file...

Please check again if this is still a problem with font-patcher 4.18.1

https://github.com/ryanoasis/nerd-fonts/blob/master/FontPatcher.zip

Please add a screenshot / image of your invocation if it still fails.

It is best to call directly fontforge with the script as parameter than to call the script via Python and that spins up Fontforge.

[saumyajyoti]

Downloaded the latest patcher and reran my existing script. It worked w/o any error. This issue seems to be fixed now.
