title: Ruby error UTF-8 to ASCII
body: <p>I have a Ruby 1.9.2 install on Centos 5.5. Every time I install a gem, I get the error </p>
  
  <pre><code>ERROR:  While generating documentation for (gem)
  ... MESSAGE:   U+2018 from UTF-8 to US-ASCII
  ... RDOC args: lib History.txt README.txt
  </code></pre>
  
  <p>The gem still installs ok, but there are certain things I can't do. Like use SproutCore, for example. I get this little gem (pun intended).</p>
  
  <pre><code>sc-init xxxx
   ~ Created directory at xxxx
  FATAL ~ invalid byte sequence in US-ASCII 
  </code></pre>
  
  <p>Anyone have any idea what's going on, and how to remedy it? Google isn't much help on this one.</p>
