[NTG-context] % in URL

I am trying to typeset a URL that has numerous “%”s in it which I am replacing with “\%”s. The problem is that while the typeset URL works, the printed URL is showing the “\%”s rather than just the “%”s. For example, \useURL [Hoyrup2007bURL] [{http://www.akira.ruc.dk/~jensh/Publications/2005\ %7BR{\percent}7D1_Folkerts_vol-1.PDF}] [] [{http://www.akira.ruc.dk/~jensh/Publications/2005\%7BR\ %7D1_Folkerts_vol-1.PDF}] produces a link that works but reads as http://www.akira.ruc.dk/~jensh/Publications/2005\ %7BR{\percent}7D1_Folkerts_vol-1.PDF I notice that “\&” behaves as it should in this context. Any suggestions or pointers to a solution will be much appreciated. I am using ConTeXt ver: 2008.04.18 14:17 MKII . Best, Alan
