Cut and paste of external links leads to zero-width character in string

[vladmihaisima@…]

When copy pasting text which includes an external link a zero width character is introduced in the text.

For example when copying from page WikiFormatting the lines in the "Links" row of the table (more specifically, the first sub-line) the Unicode character \u200b is introduced between the text in the first column and the text in the second.

This caused problems in Firefox 26.0 (Firefox 25.0 was working), when the link was: git clone ssh://user@host/project and my guess is that it can cause unnecessary frustration (not that I am aware of the problem, I can escape the links, but I did not know that previously and, even worse, it used to work).

Personally, if the only reason for the zero-width character is the icon, I would be perfectly fine without the icon.

This bug is related (but not identical with): #10668, #10865 and might have been a cause of #9529 (maybe a pasted link reached timeline)

For anybody wishing to patch their trac code is at source:tags/trac-1.0/trac/wiki/formatter.py#L710​

comment:2:ticket:11351 may be related as well. I guess maybe we need to come up with a solution different from stripping ZWSPs everywhere they are taken as form or macro input.
