title: Regex to remove consecutive sets of 1-2 characters separated by spaces
body: <p>I am regex impaired, so I apologize for that, and want to thank, in advance, whoever can help me with this.</p>
  
  <p>I have text as follows:</p>
  
  <pre><code>real text that i want to keep i e 2 2 1 i h i i i E h i L h R 9 more real text
  i e 1 i tr L h R 1 i L ? i j 1 more real text that i want to keep d i j 0 etc...
  </code></pre>
  
  <p>You can see the sections of "junk" text that occur - these are what I want to remove. I'm not necessarily looking for 100% accuracy, but I'd like a regex that can get rid of most of these sections. I consider junk text to be any section with four or more consecutive occurrences of one or two characters, followed by a space. </p>
  
  <p>As noted in the tags, I am working with c#. Thanks again.</p>
