Urgh! Sorry to see your problem. Can you give me a link to the font you want to patch?

Ah, most probably a font without latin glyphs, as font-patcher detects no source font width. And there is no code for pure Chinese font's "cell width".

An example font to work with would be good.

Ah hmm. You try to patch devicons.ttf? Most likely this is not what you want. Maybe describe what you want to do. The argument should be the font you want to patch with more icons. devicons.ttf is one of the containers that hold the icons that we want to patch into other fonts.

The actual issue (the crash) is fixed via

I close this now. If you have information with a only-Chinese-font please reopen and tell me which font it is and we can work out a solution.

The command in the report above is most likely not what was intended.

If your intention was to create a font with only all the symbols

• There is special code for the case the to-be-patched font is completely empty (instead of: has some icons)
• Use a really empty font, for example src/unpatched-fonts/NerdFontsSymbolsOnly/NerdFontsSymbolsNerdFontBlank.sfd
• Convert from sfd to ttf with command line parameter --extension ttf
• This is how patched-fonts/NerdFontsSymbolsOnly/SymbolsNerdFont-Regular.ttf is created
