title: char vs varchar for french accents (multibyte characters)
body: <p>I will have a large database with words, and one column
  of the table would have a maximum of 3 letters however
  there will be some french accents like â, ê, î, ô, û,</p>
  
  <p>An example would be Having a column that would possibly have
  [id][column2]
  1   a
  2   b
  3   vf
  4   êf
  5   t</p>
  
  <p>So they wont be fixed at all times, and sometimes some of the rows will
  have accent characters, which to my knowledge require one more byte.</p>
  
  <p>I'm thinking what would be the best option to specify for that column?
  CHAR might be faster, because they will need 3 bytes max at every time
  but often times there will be stored 1-2 bytes</p>
  
  <p>On the other hand VARCHAR is variable length, and I dont have to specify anything
  But I have read that char is better for performance, as I will be reading columns
  words very often.</p>
  
  <p>What do you think is best? And why?</p>
