### Problem Description

Hi there, I requested adding Lucide Icons Solid #1606 to NerdFonts, but it ended up creating a whole new project with over 60k icons per font! Since NerdFonts lacks a lot of icon sets, I’ve patched some of the fonts myself, but I’d rather not keep them to myself or keep reinventing the wheel.

### Desired Solution

I’m here to help with adding new icon sets to NerdFonts and creating custom ones. I also have some ideas to improve NerdFonts, like fixing glyph alignment issues (#1330) and the alignment of special glyphs. You can check out more about this and other alignment details in [icon-types-and-alignment](https://github.com/iconicFonts/iconic-fonts#icon-types-and-alignment).

### Alternatives Considered

- Add aliases to icons. I discussed this in [Improve Icon Search](https://github.com/iconicFonts/iconic-fonts/issues/87).
- When adding more icon sets and aliases, the `glyphnames.json` file will become large, so consider using `CSV` or another alternative method to manage this.
- Introduce new codepoints for the new icon sets.
- I also noticed that NerdFonts uses some iconic fonts instead of SVG icons. Why is that? Perhaps NerdFonts should use SVGs to insert glyphs instead.

### Additional Context

The main goal of this issue is to improve NerdFonts by adding new icons, enhancing glyph search, and fixing alignment issues. I’m happy to discuss any questions you have—I’m not asking for anything in return. I already have these enhancements and want to integrate them into NerdFonts. I just want to help ensure everyone can access the icons they need. If you’re interested, let me know. Thanks!
