Problem with posting links
Some time ago I had posted a link to a document that is on a Google drive but I did not look not it further at the time as other way of getting to the document where posted. This was in the thread "HP Nano Processor" recently there was a new post by someone looking for this document and much to my surprise when I found the link I had posted on a groups.io forum to the same document the link still worked so I got to wondering why the one I posted in the thread did not work.

What I found is that when posting the link here whatever formats the link was inserting 3 unprintable characters into the link, I discovered this by coping the link from the tread here and the link from groups.io into a hex editor and there the three extra characters appear.

This is the link I deliberately left the "https://" in hopes that the editor would leave it alone

"drive.google.com/folderview?id=0BwZMBH1UdIEYfkZsMllIRFN2TlowY0JzLXNGbnFtMGhyVDNKUHU0Y3VwREVmVWVfb​FdEelk&usp=sharing"

the three characters are inserted right after ...mVWVfb

This is the original link

00000080 72 69 6E 67 20 20 20 20 20 20 20 20 20 20 20 20 ring

Note the extra byte between 0x6A and 0x71.

RE: Problem with posting links
%E2%80%8B is Unicode U+200B, "zero width space."
No clue why that would be getting inserted...

RE: Problem with posting links
Probably to break long words. A feature of the forum software?

abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzab​cdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcd​efghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdef​ghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz

Yes, they are inserted after every 80 characters.

RE: Problem with posting links
Yep! that's a problem, in the meantime you can place it within a code block, you loose the automatic link but at least you get the correct url.
Code:

RE: Problem with posting links
This issue also occurs when sending PMs. I've confirmed that Sylvain's code block solution works around the issue in PMs.

CC41 coming soon!
