Let's say I want a link to plot x+2 in Wolfram|Alpha. I need to catenate "http://www.wolframalpha.com/input/?i=" and "plot+x%2B2". Is there any way already available in ConTeXt to translate reserved characters like "+" to the percent-hexcode "%2B"? Something like \encode[plot x+2] would become plot+x%2B2 Or more generally, some languages have a query constructor like this \queryURI [http://www.wolframalpha.com/input] [i=plot x+2] which would construct the URI http://www.wolframalpha.com/input/?i=plot+x%2B2 I could write my own, of course. But no need to reinvent the wheel.
