PMMP 4. When I use bold text in sendTitle, sendPopup, etc. (except for sendMessage) empty spaces appear; reset at the end of the line does not help either. Appear only in Cyrillic. How to remove it?
I'm not a credible source to quote, but this looks to me to be a client-side issue. Just in case, can you give us the raw string you pass as an argument? I assume does not have these extra spaces on each side because, as you said, it does work through the sendMessage method. I don't see how and why pocketmine would handle your string differently based on the charset. If you have verified this issue to be related to the client, then your best bet is to submit this issue https://bugs.mojang.com/projects/MCPE/summary
