Steps to reproduce:
1.Create some events with Chinese title, their titles show normally in /admin-ng/index.html
2.But these Chinese titles show as ??? in Event detail->Workflows-Details, the Series UI on /engage/ui/index.html, ffmpeg-generated cover-image, REST invoking returning results ( i.e, Pumukit 2 integration).
They should show normally.
Workaround (if any):
I guess that's because non-uniform encoding between MySQL database and Java code.
