After upgrade sevral of my applications opened with Japanese text in stead of English. Easy way to change that: just go to System Preferences Language and Area and change in the "Prevered Languages" panel by dragging the "English" to the top or second position.
There are in my update several other preferences, that were not respected, so just check all of them.
