title: _Actual_ Twitter format for hashtags? Not your regex, not his code-- the actual one?
body: <h2>Update: Use Twitter's Entities if you can- they figured it out for you as well as other items. My case is that I just have the tweet without entities and all the extra metadata</h2>
  
  <p>I've spent what I consider an unreasonable amount of time trying to find the <em>actual</em> format for hashtags.</p>
  
  <p>As far as my searching can tell- Twitter has not published one.</p>
  
  <p>I know that many people have come up with regex's to parse them, however, your lib's regex is not my lib's regex and maybe I don't like yours anyway.</p>
  
  <p><strong>So I'm asking- is there any actual official spec?</strong> I don't want a regex answer, I want a BNF or something similar. Or minimally- a complete list of delimiters.</p>
  
  <p><em>Additional difficulty points</em>- grabbing them from random unicode messages (non-English) text is important too.</p>
  
  <p>Note: I'm quite aware of entities and they aren't applicable to my case (months of twitter messages stored in a db).</p>
