Anyone know for sure the set of filepath characters safe for hyperlinks? I'm seeking workaround for the failure of [, { and # (https://www.msofficeforums.com/word/...03-2007-a.html).

Or... a scientific way to find out? Given I've found at least two modes of fail, I would be reluctant to rely on the results of trial and error.

Fun fact: ¦ is safe though | is disallowed. My UK keyboard has these two transposed, for some reason.
