In the ACP if we choose a different location other than the default for the "Emoji Source", what is the naming convention that the emoji images should use?
To answer my own question.... it's just {CODE POINT}.png so something like U+1F600 would be 1f600.png so now I can serve the images locally instead of relying on the JoyPixels CDN.
.... and for multi code point values, use dash as the separator and not underscore.
