Glibc and locales incompatibility in Debian Wheezy?

Question

linux

Good time!
Need help with glibc library in Debian Wheezy.
Foolishly, I installed version 2.19 from testing, which upgraded some libraries and removed locales, because it requires libc6=2.13
Due to the removal of locales, several necessary packages stopped working, incl. my own.
Please help with downgrading libc6 to 2.13-38+deb7u8 or restoring locales.

Answer 1

Show /etc/apt/sources.list
Generally speaking, Debian Wheezy is now old stable and you have installed packages from stable, not test
Or just upgrade to stable.

Answer 2

So install what was removed back, for locales:
Well, the rest of the packages by analogy, specific versions will return, they should still be available.
