Comment (by SergeyBiryukov):

 And if the title is in Cyrillic, it gets urlencoded and becomes completely
 unreadable, e.g. `Изображение 1` turns into
 `%d0%98%d0%b7%d0%be%d0%b1%d1%80%d0%b0%d0%b6%d0%b5%d0%bd%d0%b8%d0%b5%201`
 :( Same for Arabic, Japanese, and other non-ASCII alphabets, I guess.

 Confirmed on all releases [38538] was backported to: 3.7.16, 3.8.16,
 3.9.14, 4.0.13, 4.1.13, 4.2.10, 4.3.6, 4.4.5, 4.5.4, 4.6.1.
