Hyperlinks Containing Parentheses?

Aaron Turner January 3, 2018

My company has started using Trello, and I've encountered an issue with the Hyperlinks: parentheses.


I have a really ugly URL that I'm trying to hide behind a link, but because the linking mechanisms function off of the parentheses, the process is failing.






Note the existence of parentheses in the URL. When I try to turn this into a link, Trello fails:



Gives me: Issues%20AND%20project%20%3D%20SSDM)


It appears that the double parentheses near the end are causing the link to end before I actually want it to.


Is there any way to escape the parentheses, or force the linking to continue until I want it to end?

You could escape the characters by replacing them with their hex equivalent.  Just as the spaces are replaced with a %20 you can do the same with the parenthesis.   If you change the ( into %28 and the ) into %29 the URL should still be valid and in turn you can eliminate those characters from the URL itself.

There is a complete chart on the ASCII to HEX character conversion that might help to understand this better in

Wow....I do that particular replacement all of the time, but then I didn't even think of doing it this time.


That worked, and the links now work. It's not very "pretty" of a solution, as we have to manually edit the copied links each time, but it's working, so I'll be happy.


Thank you, Andrew!

This just helped me out tremendously when I didn't understand why a mailto link I had made was not working properly. Thank you!!
