  and avoid the conversion. As a bonus, this date format is compatible with the Javascript date parser, so you can use ''new Date(doc.created_at)'' in your client side Javascript to make date sorting easy in the browser.
  
+ === String Ranges ===
+ 
+ If you need start and end keys that encompass every string with a given prefix, it is better to use a high value unicode character, than to use a 'ZZZZ' suffix.
+ 
+ Rather than:
+ {{{
+ startkey="_design/"&endkey="_design/ZZZZZZZZZ" 
+ }}}
+ 
+ You should use:
+ {{{
+ startkey="_design/"&endkey="_design/\u9999" 
+ }}}
