How do I prevent auto-generated links in the GitHub wiki?

Question

On a GitHub wiki page, if I type:

www.foobar.com

GitHub automatically assumes this is a URL and makes the text a hyperlink to http://www.foobar

Answer 1

Would suggest to use zero-width no-break space.
In HTML could be used as Unicode char reference:  or 

Benefits are:

• prevents autolinks (obviously)
• invisible
• no unexpected line breaks
• readable in source

Examples

For urls insert between http and :
https​://example.com/ → https​://example.com/

For emails insert after @:
user@example.com → user@example.com
