Wiki page content Link is removed

Question

Hi all, 
 I created wiki page, I added Link with Guid ( ex. https://test.de/sites/local_wiki_dokumente_test_10/_layouts/15/WopiFrame2.aspx?sourcedoc={ef7b8a89-68b4-4fd7-a7bf-b79e468dfe74}&action=edit ) 
 In Edit-mode (before save) link works but after saved link is removed. 
 Do you know any rules any settings restriction for {guid} in url? 
 Thank you very much 
 kind regards, 
 Heeky

According to RFC 2396 curly braces are "unwise" characters to include in urls without being encoded. I'd recommend either encoding them or using a different character (or just removing it, the guid should be interpretable on the other side via usage of the query string without the need for the braces)
