Hi Hans, I have the following sample: \setupinteraction[state=start] \starttext \startTEXpage[offset=1em] \attachment [file={https://eur-lex.europa.eu/legal-content/% ES/TXT/PDF/?uri=CELEX:02010L0040-20180109}, name=one.pdf, color=orange] \attachment [file={https://eur-lex.europa.eu/legal-content/% ES/TXT/PDF/?uri=CELEX:52011DC0144R(02)}, name=two.pdf, color=magenta] \stopTEXpage \stoptext Because of the parentheses in the file address, the second file isn’t attached, due to the use of parentheses (sorry, but I cannot avoid this in their address). curl is also unable to download the second file unless an output name is specified (with --output or -o). Would it be possible that ConTeXt could handle the second address with parentheses to attach the file to a PDF document? Many thanks for your help, Pablo -- http://www.ousia.tk
