### `Option 8: Clone the Repo`
### `Option 8: Font Fallback`
Most systems have a mechanism to search for an alternative font when the current font does not
have a glyph that is needed. For example you edit a Latin text and insert a Chinese character,
that glyph is taken not from your active font (it does not have it) but from some other font.
For this font fallback you can use one of the `SymbolsOnly` fonts.
For fontconfig based systems like Linux you can improve the behavior with the
`10-nerd-font-symbols.conf` configuration file, that needs to be manually installed.
* Pro: One symbol font is sufficient for all text fonts
* Con: Scaling and placement of the fallback symbols can be hit or miss
### `Option 9: Clone the Repo`
> Best option for **full control**, **all** or **some** of the fonts, or **contributing** to development.
