How To label an image with an emoji using ruby rmagick with imagemagick? A: Use an XML entity escape e.g. &x1234; with the pango text renderer

For my 3 followers :-) who want to create images with emojis with ruby :-).
Sadly copying and pasting the emoji doesn’t work.
Neither does specifying the Noto Color Emoji font (imagemagick fails with “cannot read font”).
But oddly, copying and pasting an emoji into the command line e.g. magick or convert work with copy/pasted emojis.
Finally, I could not get the rmagick/imagemagick combo to work without using pango which uses XML escapes for unicode characters like emojis.

Code

# convert pango:'a🤳Hello! 😀How are you?' example.png # Selfie emoji is 1F933
require 'rmagick'
image = Magick::Image.read('pango:&#x1F933;The <b>bold</b> and <i>beautiful</i>').first
image.write('pango.png')
