Text in anvil changes to pound symbols

Hello me again, It is that it does not seem fair to me that I have bought minecraft and have more problems than my friends who have it pirated. It's like they want to do it on purpose To get better APKs Free I don't understand But, really The problem is the same I get those symbols When I type a command Or change the name To an item ########## You always wear that No 1 time, Forever.

 

Extra fact It only happens to me at the Realm
