Combined flag of language: Russian

Flag of Russia is used as symbol of Russian language. It is good inside Russia, where minorities accept state flag and state language at the same time. However, in Belarus or Ukraine there are Russian speakers who shouldn't be loyal to Russian flag. Not to mention non-Slavs in post-Soviet countries that are using Russian in international contact. The de facto language union of Russian is the Commonwealth of Independent States. Pure flag of CIS is not symbol of language, rather of organization, but this flag, similar to this Italian, should work well.
