To make sure that it will solve the problem, I have applied the solution
you suggested.
Copied the source and changed '^direct' to '^DIRECT' and builded.

The proxy problem is solved, but the package-install gpg problem I
mentioned (Error while verifying signature archive-contents.sig:) is still
there.

Also I found another weird bug related to this:
with English language environment visit 'https://www.google.com.tr' using
eww, you will see the Turkish characters correctly.
with Turkish language environment, do the same thing, you will see weird
characters instead of Turkish characters.
