It looks like your problem happened due to the fact that during INSERTs, the connection to the database was made with the wrong encoding (charset). You need to determine (via "SET NAMES='CP1251';" for example) what encoding was used, and with this encoding to read these incorrect data, then they will be correct. And then, through the connection with the correct encoding, overwrite them, and everything will fall into place ...
