Is there a reason [[:Category:Brooks & Dunn songs]] has a warning at the top saying "this category appears to be empty" when it's clearly not? I tried a null edit and nothing fixed it. Anyone know what might be causing this? <span style="color:green">'''Ten Pound Hammer'''</span> • <sup>([[User talk:TenPoundHammer|What did I screw up now?]])</sup> 18:34, 11 August 2022 (UTC)
:{{re|TenPoundHammer}} It's caused by [[:Template:Songs category]]. How to fix ''that'', I don't know. [[User:DuncanHill|DuncanHill]] ([[User talk:DuncanHill|talk]]) 18:42, 11 August 2022 (UTC)

::: {{ec}} According to the wayback machine, the "empty" warning has been present since [https://web.archive.org/web/20161112133405/https://en.wikipedia.org/wiki/Category:Brooks_%26_Dunn_songs at least 2016]. The behavior of {{tlf|PAGENAME}} encoding certain special characters has been documented on MediaWiki.org since at least 2011 (originally added at [[mw:Help:Magic words]], later moved to [[mw:Manual:PAGENAMEE encoding]]). Looks like a misfeature rather than a bug. [[User:Pppery|* Pppery *]] [[User talk:Pppery|<sub style="color:#800000">it has begun...</sub>]] 18:53, 11 August 2022 (UTC)
