Using Material Icons in RichTextLabel

Example code of using emojis in RichTextLabel (included in addon: res://addons/material-design-icons/examples/LabelWithIcons.gd):

@tool
extends RichTextLabel

@export_multiline
var text_with_icons : String:
    set(value):
        text_with_icons = value
        bbcode_enabled = true
        text = MaterialIconsDB.parse_icons(value)

    get: return text_with_icons

func _ready():
    bbcode_enabled = true
    text = MaterialIconsDB.parse_icons(text_with_icons)

This is the result of the above code, with text_with_icons = "Label with icons [icon:image-outline]"
