Is there a different syntax for commenting with links that contain parentheses? I tried something like this:

[my text](

And that yielded this in the comment:

my text.aspx

It's different in comments... like so – Austin Salonen May 7 '10 at 21:57
my text <-- escaped using %28 and %29 – Jon Seigel May 7 '10 at 21:58
For Microsoft links, often you can just remove the part in parenthesis, and the link will still work – Robert Harvey May 7 '10 at 22:49
In fact, it's best to leave off the parenthesis part for MSDN links. That way, they'll always link to the latest version. Try it without the parens, first, to be sure. – John Saunders Jan 30 '11 at 3:35
@balpha isn't this a feature request more than a bug? Looks like you added new feature of supporting one level of parentheses rather then fixing a bug. No? – Shadow Wizard Jun 18 '12 at 8:06
@ShaDowWizArd I'm not to hung up on the distinction between the two in this case, both have a point. Also note that this change was made ages ago; I just noticed this question (because an old dupe just floated to the top of meta). – balpha Jun 18 '12 at 8:09
@balpha OK fair enough. I was thinking to add this to the feature change log what do you think? – Shadow Wizard Jun 18 '12 at 8:31
@ShaDowWizArd The change is from January 2011, so it's a stretch to call it recent -- but do as you please :) – balpha Jun 18 '12 at 8:41
@balpha being a complete log, I couldn't resist editing it with this. Easier to find when something was done. :) – Shadow Wizard Jun 18 '12 at 9:06

It's the same syntax, but rendering balanced matching parens is quite expensive in regex, and the comment regexes are run every time the post loads and displays -- so the support in comments isn't as good as in posts. We do however support one level of balanced parentheses, which covers your case.

As Jon noted, use %28 and %29 to encode the parens in cases where they aren't balanced or are nested more than one level deep.

I cannot get this to work with the following link:‌​.file.Path, java.nio.file.Path, java.nio.file.CopyOption...) According to what I've read, it should work (there is only one pair of parens). I have tried to use %28 and %29, but it's not working. Is it possible to include a link when the URL ends with a paren? – jahroy Jun 13 '13 at 22:16
