I've recently posted up an answer to a question. My answer contains three links, each of which are preceded by punctuation rather than whitespace. All three of the links have a mysterious space inserted between the link and the punctuation symbol.
If you go to edit my answer, you'll see that there are no spaces:
woff[doesn't work on IE8 or various mobile browsers], whereas
eotonly works on IE.
svg[doesn't work in IE8 or old versions of Android Browser].
Here is a screenshot in case my report isn't clear (or for future users after this issue has been resolved):
