Thank you again for your quickly  answer. Yes, this is bug Android OS to the Greek language. As long as I have your permission, I will translate these specific words with capital letters in crowdin.net, so that to help as and another users from Greece, for the uniformity for the application.

Of course the app is very very good.  Congratulations!

Thank you

Thank you for your answer. The capital letters doesn't appear correct . For example: ΠΕΡΙΓΡΑΦΉ the correct is ΠΕΡΙΓΡΑΦΗ with out mark in the letter H. Probably the application included in code android:textAllCaps=true. Anyway I will try to fix the Greek language in link you have give me.

Thank you
