title: Check if MyString[1] is an alphabetical character?
body: <p>I have a string, lets call it <code>MyStr</code>. I am trying to get rid of every non-alphabetical character in the string. Like, in IM's like MSN and Skype, people put their display names like <strong>[-Bobby-]</strong>. I would like to remove everything in that string that is not an alphabetical character, so all I am left with, is the "name".</p>
  
  <p>How can I do that in Delphi? I was thinking about creating a <code>TStringlist</code> and store each valid character in there, and then use <code>IndexOf</code> to check if the char is valid, but I was hoping for an easier way.</p>
