 3. On linux, you could also copy the font and its license to the system fonts by running `sudo ./install.nu`

 If you want to be able to fuzzy find specific emoji from the Mutant Standard set, you could try running `export_memoji_codes.nu`  
 The output text file will have the format of `emoji character` `space` `emoji shortcode` (so a line may be like this: `😸 cat_smile`)
