About Cyrillic... I still have Pb Classic and switched to Rockpool, then updated FW to latest one. For sure have no cyrillic at all. Then I've tried to install custom FW with cyrillic - and get watches in with [] instead of all symbols. After going to recovery mode and installing native FW from another device I've got Classic with latest FW... and cyrillic symbols. So far all notifications are shown correctly in both latin and cyrillic.
