+~~~~~~~~~~~~~~~~~~~~~
+
+By default, the ``[ul]`` tag uses the ``U+2022`` "Bullet" Unicode glyph as the
+bullet character. This behavior is similar to web browsers. The bullet character
+can be customized using ``[ul bullet={bullet}]``. If provided, this ``{bullet}``
+parameter must be a *single* character with no enclosing quotes (for example,
+``[bullet=*]``). Additional characters are ignored. The bullet character's
+width does not affect the list's formatting.
+
+See `Bullet (typography) on Wikipedia <https://en.wikipedia.org/wiki/Bullet_(typography)>`__
+for a list of common bullet characters that you can paste directly in the ``bullet`` parameter.
