--------------------------+-----------------------------
 The caption shortcode (maybe shortcodes with start and end tags in
 general) break when "lower than" character is inserted manually:

 {{{
 [caption]<a href=""><img class="" src="" alt="Caption with special
 character lower than < breaks WP" /></a> Caption with special character
 lower than < breaks WP (inserted manually)[/caption]
 }}}

 Using the UI it is escaped correctly with {{{<}}}
