retro-pixel-font VS fonttools

The tool parent and sibling comment listed allows you to do basic subsetting [1], and generates the formats you need. If you do this more often, it is of course useful to learn how to do this yourself. A commonly used tool is pyftsubset, part of fonttools [2]

I know fontforge doesn't support OTF-SVG, but I'm actually using it for creating OTF-SVG from scratch. Is anyone willing to help me with this issue? https://github.com/fonttools/fonttools/discussions/3229

I'm having this issue and maybe here someone can help me.. https://github.com/fonttools/fonttools/discussions/3229

In short, I draw glyphs in png and use python to build fonts (by https://github.com/fonttools/fonttools ). I agreed on some rules and then everything became simple. No required professional font editer.

If you have FontTools successfully installed, there is also a bundled script that's similar to what justinpenner's code does, without the built-in directories; you can find it at https://github.com/fonttools/fonttools/blob/main/Snippets/layout-features.py

What I like the most is that you can also download google-fonts and convert them automatically. Webfont-Kit-Generator uses fonttools (written in Python), that's pretty cool too.

A drawback to icon fonts is that by default, you are carrying all of the glyphs in an icon font along for the ride. You can mitigate that by using a tool like fonttools to strip out the unused font glyphs.

If you're interested in learning more about how variable fonts work, I can point you to all sorts of tools and other resources. For example, fontTools includes a command line tool called ttx that converts any standard font format (ttf/otf/ttc/otc/woff/woff2) to a human-readable XML text file. You can also inspect variable and static fonts easily with online tools like Wakamai Fondue and Samsa.

If you want to look inside a font file, you can use the ttx command line tool (included with fontTools) to convert binary fonts to human-readable XML format. You can also open them in a font editor like FontForge or Glyphs if you want a GUI, but font editors may not show you everything that's inside the file.
