Good and also clean up the profiles with this character
Validating feels the wrong approach better just to "clean" the LNAB or name fields.... from those bad characters..... Even I will be confused with an Error message "Sorry sir you are adding an invisible character please try again"
Feels like Aleš found more errors see comment 381478#c381478 I guess it's a small problem as you "only" get problems when you have external linking and do copy paste of an URL. Inside the Wikitree echo system I feel we can handle visible and nonvisible characters with no problems.....
Lesson learned is that suggesting a merges and trying to explain the hidden character problem and also please merge to a higher number yada yada is not on my list of things I have succeeded to do.......
