Zero-width space with URL is not separeted

[tribela]

In Korean (and some other languages), We have not to add space between noun and postpositional part.
For example:
커피숍에서 (커피숍 = Coffeeshop, 에서 = at)

So I use U+200B(zero-width space) to separate URL part like "http://test.com/<200b>에서"(It means "at http://test.com"). Most times smart link doesn't recognise that as part of URL.
But in Mastodon, I tried U+200B and U+FEFF(It also zero-width space), But it doesn't separate link and normal text part.

Meanwhile, hashtag was separeted with zero width space (toot link here):

(Hashtag was separated, But not URL)
I also tried U+000B(vertical tab, But usally used for this kind of job), It works fine in Firefox, But it renderd incorrectly in Chrome. (toot link here)

Vertical tab character is rendered as ♂(U+2642 male symbol).

• This bug happens on a tagged release and not on master (If you're a user, don't worry about this).

Still valid, just encountered this in an entirely different manner: copied my other toot (in Russian) using Tusky and in the process somehow accidentally inserted a zero-width space at the end of the URL, which was picked up by Mastodon as part of the link destination and, well, broke the link.
