Grigory,
I also do not know what to do, but try this post and this thread as a starting point as it's about the translation files and a place where they are available from: https://forums.codeblocks.org/index.php/topic,1022.msg159075.html#msg159075
Good luck.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I don't know what to do with this file. Codeblocks doesn't ship any translations. The translations are kept/provided by a separate project.
If I'm wrong feel free to correct me.
