+Why are there graphic-based smileys at all, when Unicode supports most of them directly?
+
+What Unicode doesn't support can be handled by FontAwesome or a little CSS. 
+
+Keeping font-based solutions to emojis allows them to scale naturally with the fonts. An emoji in the title becomes a different size than an emoji in paragraph, or an emoji in a subscript.
+
+Here's a smileys.mdwn file that doesn't use any graphics at all:
+
+<pre>
+This page is used to control what smileys are supported by the wiki.
+Just write the text of a smiley to display it.

+* \\{3}	[<span class="priority-3">𝟛<span>]
+
+For example: {x} B) {x} {3} :grin: :-1: 
+
+----
+
+To change the supported smileys, just edit the lists on this page.
+Note that the format is important; each list item should start with the
+text that is turned into the smiley, escaped so that users can see what
+produces it, followed by a [[ikiwiki/WikiLink]] to the image to display.
+
+/!\ Bear in mind that the link to the image needs to be written in a way that
+will work if it's copied to other pages on the wiki. So be sure to include the
+smileys directory in the path to the file.

+Here's the patch to smiley.pm:

+
+As you can see, it keeps the [] characters around the smiley. This can be useful if it renders to nothing in the browser -- particularly in the CSS-based solutions. 
+
+It keeps the same data structure, but images get a "[" prefix to them as a marker. Since I minimized the changes to the regex, the trailing "]" is still dropped.
