Hi,
We have a test day event for Internationalization on f22 as usual to make sure if f22 has any issues around i18n.
Please join Freenode #fedora-test-day and try if your primary language works on f22 when you have a bit of time.
Test cases and details are:

All of feedbacks are valuable. even if you don't have a time today, you can try it anytime if you like.
