Some translations may be incomplete, and certain applications may not support your language at all. Any untranslated text will appear in the language in which the software was originally developed, usually American English.
There are some special folders in your home folder where applications can store things like music, pictures, and documents. These folders use standard names according to your language. When you log back in, you will be asked if you want to rename these folders to the standard names for your selected language. If you plan to use the new language all the time, you should update the folder names.
If there are multiple user accounts on your system, there is a separate section for the Login Screen in the Region & Language panel.
