URLs Containing %C2%A0
I am using RoboHelp 2020.6.76 to generate frameless help output. Earlier this week, I and/or RH somehow generated two URLs that appear to have included a non-breaking space. I don't know how this is possible, and I cannot reproduce it (at least not intentionally). I didn't notice this issue until sending the URLs to marketing for a release notification e-mail. Both URLS contained %C2%A0. I tested the links, verified that they worked, asked internally if anyone thought that might cause an issue, and got no response--until after the e-mails went out and customers started contacting us to tell us the links didn't work. In fairness, it looks as if the marketing e-mails embedded the links in longer links, probably meant for tracking purposes, and appear to have stripped out the percent signs. Even after I put them back in, the marketing-generated links did not work. When I looked at the topics in the help project, there appeared to be a blank space in the URL. The generated output was replacing the blank space with the %C2%A0. I corrected the topic links, replacing the blank space with an underscore. Then I thought I should probably keep copies of the topics with the blank space in case those links were working for anyone. When I regenerated the help, the system replaced the blank space in the URLs with %20 (which is what I expected to see in a URL for a blank space). At this point, I added two more copies of the topics to the project where I purposely put %C2%A0 in the URL in place of the blank space (so that anyone for whom those links might have worked previously would still have working links). When I generated the help, those links did not work. When I had IT copy the new set of help files to Production, I had them keep the two files for which the system appeared to be replacing a blank space with %C2%A0. That worked. I'm at a loss to explain it. I searched the Internet and found references that C2 A0 represents a non-breaking space. I also found one reference that said the URL will show %C2%A0 if a hidden folder is associated with the URL. That said, questions: Has anyone else seen this? Does anyone know what causes it? Is there a way to prevent it from happening? Thanks!
