Backup messages displayed with wrong encoding

Hello,

I am using pgAdmin3 1.14.1 on Windows 2008 R2 (Russian locale, SBCS
Win1251) with Postgresql 9.1.2.
Having database with UTF-8 encoding and objects, those names contain
non-ASCII (Russian) characters, I get non-readable object names when
performing backup in pgAdmin3.

I think it's happened because pgAdmin assumes that pg_dump always
streams output using current locale encoding. But it's not the case,
cause it can be a database encoding (by default) or the encoding
specified explicitly in frmBackup.

Thanks,
Alexander
