Answer 1

You’ve messed up your character sets somewhere: the table, the connection, the output, or some combination of these is using an incorrect character set – so make sure they all match and use a character set that can represent your characters – UTF-8 is generally the best choice, because it can represent everything.

It is not possible to be more exact than this, because you have not provided any information about which character sets each of those things are using.
