title: AES_DECRYPT() and AES_ENCRYPT() in MySQL with Polish characters
body: <p>I have a MySQL database which is configured to receive a data with polish characters (f. ex ą, ę, ó, ł, ń etc.).</p>
  
  <p>Now I want to send data with these Polish characters to a db using <code>AES_ENCRYPT()</code>, and then get them from there using <code>AES_DECRYPT()</code>.
  My problem is that I receive a byte[] array in C# which has X elements where X is length of text I receive. And every single array element has an ASCII code of an character it represents. I could easily convert it to text using Encoding Class, but I won't get Polish characters in output text.</p>
  
  <p>F. ex.: </p>
  
  <p>I send <code>AES_ENCRYPT('ąąą', '123')</code> to db.
  I get <code>AES_DECRYPT('sql command','123')</code> and I get <code>byte[]</code> which has 3 elements, everyone with '97' value which represents <code>'aaa'</code> - NOT <code>'ąąą'</code>. 
  How to use <code>AES_DECRYPT/ENCRYPT</code> in a way which allows me to send/get polish characters to my DB?!
  Or how to get string output from aes_decrypt() instead byte[]?</p>
