How to get readable string from mysql with node.js?

When user register, i save its name in mysql (russian name in database
seems like - АрминсН). When I take data from database with PHP and
print out, it works good (show russian letters), but when user connect to
node.js server (using socket.io), make mysql query (using node-mysql
module) and receive data from query, then his name seems like -
АрминсН. How to get readable letters?
