At https://forum.winehq.org/viewtopic.php?p=146295#p146295 I used a UTF-8 emoji
"????". Emoji are part of the Unicode standard but for some reason phpBB tries
to replace it with an SVG.

<div class="content">If there was a like button I would like your reply! <img
alt="????" class="emoji smilies" draggable="false"
src="//twemoji.maxcdn.com/2/svg/1f60a.svg"></div>

..ironically the alt renders correctly (for me anyway).

twemoji.maxcdn.com is a dead host so we get the lovely "failed image" icon.

Apparently it's a phpBB bug that isn't yet fixed, but can we work around it?

I don't think the reliance on third-party SVGs is necessary, especially these
days.
