    Yep, it sure does. Please don't put that back into the title while I fix it! I've edited at the database level to make this question available. – Marc Gravell Aug 24 '15 at 14:17

    @Braiam no, it isn't; the fundamental problem is outside of our part of the stack: we can't make IIS happier. What we can do, however, is to not generate links that won't work. Which is what is now the case. And in particular: to not force a redirect to a broken url. Hence why you can now view this question. – Marc Gravell Aug 24 '15 at 15:07
  • @Andy: I wondered how the question had five votes when my best URL hacking couldn't get it to display.... – Nathan Tuggy Aug 24 '15 at 19:05
  • @MarcGravell then, why other web servers allow such combination? AFAIK, RFC 3986 allows any unreserved character using the percent-encoding method. – Braiam Aug 24 '15 at 22:15
  • @Braiam because software often has glitches in a few edge cases – Marc Gravell Aug 24 '15 at 22:44

There are some Unicode combinations that IIS just hates and refuses to play with no matter how much you %-encode them. You seem to have found another one! Congrats.

This will be fixed in the next build.
