Comment (by dd32):

 > If a such function exists - esc_attr() then logically it should also
 exist a reverted function like capture_attr() or cap_attr() for such task.

 esc_attr() is designed for escaping data to be used in HTML attributes,
 There are very rare cases where you should need to convert the data back,
 If you're saving something using esc_attr() and then later need to convert
 it back, you're probably doing it wrong, or using the wrong form of
 sanitization.

 > this function does not work for single quote.
 When used in it's compatibility mode (default) it doesn't, however, like
 most PHP functions, it has a range of configuration parameters.
 {{{
 echo html_entity_decode( '< > & " '', ENT_QUOTES ); //
 outputs < > & " '
 }}}
