This looks like an error to me. If I type https://duckduckgo.com/?q=Org+mode+%252B+Worg in my browser, I get "Org mode %2B Worg" as the search string. It should be the same when opening the link from an Org document. These URI are /not/ equivalent. > The same happens when using link 1) of the HTML export.

It looks as we're trying to paper over an Org problem here, which is the redundant link escaping that happens when calling `org-insert-link' (C-c C-l). AFAICT, there are two reasons for Org to escape a link: when the link contains either "]]" or multiple consecutive spaces. The former obviously breaks Org link syntax. The latter doesn't survive a call to `fill-paragraph'. Alas, Org handles it the wrong way, by using a mechanism that cannot be properly undone; you cannot possibly know how many times the desired URI has been encoded, if at all. Moreover, this mechanism isn't user friendly, i.e., you cannot reasonably ask a user to encode an URI on the fly when jolting notes. I can see two ways out: 1. Do not escape anything. This prevent any link with a description to contain either "]]" or multiple spaces, but these requirements are so uncommon we probably shouldn't bother. 2. Use a different internal escape mechanism. By providing our own simple escape mechanism, e.g., \]\], we can solve the issues raised above. In any case, Org should not create something as https://duckduckgo.com/?q=Org+mode+%252B+Worg if the real URI is https://duckduckgo.com/?q=Org+mode+%2B+Worg WDYT? Regards, -- Nicolas Goaziou
