title: Chrome form POST shows "(unable to decode value)" and database stores it as a question mark
body: <p>I have a test site and test DB both set to <code>windows-1252</code>.  When I type <kbd>Alt</kbd>+<kbd>234</kbd> into Chrome it puts this symbol in the field: <code>Ω</code>.  And when I submit the form it posts and stores it as <code>&amp;#937;</code>  I'm assuming this is the browser saying "<em>hey, this isn't in the specified charset but I do know of an html equivalent, so I'll post that instead</em>".  Fine.  The symbol appears properly after saving, I can save, save, save, and it always appears fine.  But if I try the same thing with <kbd>Alt</kbd>+<kbd>230</kbd> the browser does not submit it's html entity value of <code>&amp;#181;</code>.  Instead I see "(unable to decode value)" when viewing the POST in the Chrome DevTool window.  And it ends up being stored in the database as a question mark.</p>
  
  <p>Why does it treat <kbd>Alt</kbd>+<kbd>234</kbd> (<code>Ω</code>) differently than <kbd>Alt</kbd>+<kbd>230</kbd> (<code>µ</code>)?</p>
  
  <p>I know I should switch to UTF8 but I still would like to know why it is functioning this way.  Thanks!</p>
