Q:

Dont know how to select a few records from a table as utf8

I don't have phpMyAdmin installed in my web site.
Sometimes I was doing some select SQL command at the backend, 
but when I typed in this command to show all records from table Users:
select * from Users;

The records were printed as ???? | ??? ??? ??? |.
I don't want to make any permanent changes to the charset in the database,
so, how is it possible to temporarily displayed a few records as utf8 when needed?

A:

> CONVERT()
provides a way to convert data between different character sets
example:
SELECT CONVERT(newvalue USING utf8);
