I did a forum search… original issue was opened March 2020. As I said, I thought this had been fixed so I opened it again. You can merge my example to the other thread if you like:
Can the priority on this one be bumped higher? Really bummed to see a display bug like this living for so long.
As I mentioned in my original post, the problem affects a set of singles by ⣎⡇ꉺლ༽இ•̛)ྀ◞ ༎ຶ ༽ৣৢ؞ৢ؞ؖ ꉺლ (aka Kieran Hebdan). Seemingly the forum software can get it right, as do a lot of other online sources, but Roon’s attempt is a mangled mess.
This isn’t a glitch that a reboot will fix - I’ve rebooted quite a few times since I posted in 2020 - it’s Roon failing to render the weird font Kieran Hebdan is using for his alter ego and the titles and tracks of his singles.
I’ll be honest, I’m still not all that bothered by this as Roon’s messed up version is no less comprehensible than the original but, as @ipeverywhere mentioned, it’s a shame that this problem has dragged on for so long.
