There is a config to set specific chars by file extension?

[FrancoBujakiewicz]

If you are using nerd fonts yazi automatically will set they to many files to represent they by its file extension. But not all, some file extensions don't have a glyph associated. Is there a way to config it to assign a character for specific file extensions or also override the existent?

e.g.

(If you are using nerd fonts in the browser you will see the icons) 

.lisp = ""
.rs = ""
.css = ""
