Members of my alliance and I have had the same experience with Revenge attacks. I don't know that we have noticed it being only with Asian characters in the names or not, but something big happened recently. I agree with the other posts: nobody can be on this game every minute of every day. Besides that, when I'm in the game, I have to constantly respond the the message I get asking me if I'm "still there" and I have to press "reload", which basically clears my screen and starts as if I am loggin in. It is a frustrating issue for all involved, however, it really needs to be addressed .
Could you not have a group of players "beta" the game to track this issue rather than have dozens of unhappy players generalize, or even be specific but it only a couple of players who really "track the issue" with the information you need to solve this puzzle? Those doing the "beta" would track all of the EXACT specifics of the info you need, and they would revenge attack everyone (give the "beta" players a gift of some sort, crowns or gold or food, or whatever). You could do it as "blind research." In other words, have an opposite group of "beta" players with a second account specifically for this issue. They would do the attacking and the game could try different possibilities: non-Asian player use Asian characters/fonts, Asian teams use Asian fonts and non-Asian fonts. It wouldn't take a lot of time to do this if you have dedicated players as attackers and defenders, Asian and non-Asian fonts/teams, etc. 1-2 weeks could give you plenty of data.
Just a suggestion respectfully offered.
