The new tagged biblography export is very nice, but there is a routine (marked UGLY in the source) that causes processing to fail with otherwise-valid input. The failure message is

...eXt/tex/texmf-context/tex/context/base/mkiv/back-exp.lua:3889: invalid capture index stack traceback:         [C]: in function 'gsub'

...eXt/tex/texmf-context/tex/context/base/mkiv/back-exp.lua:3889: in function <...eXt/tex/texmf-context/tex/context/base/mkiv/back-exp.lua:3747>         (...tail calls...)

and two URLs which cause this problem are:

   url         = {http://www.jerwood-no.org.uk/pdf/Dunning%20Kruger.pdf},    url         = {http://oll.libertyfund.org/?option=com_staticxt&staticfile=show.php\%3Fcollection=46&Itemid=27},

These URLs caused no problem with PDF output  or in the previous exports, although they were not printed and exist only in the bibliography.

it's a side effect of gsub interpreting its replacement text so i need to adapt that bit

Do I need to protect the special characters in the bib file, or is this a problem with the UGLY code? no, the code is marked ugly because i don't like it being done that way
