I came across this question on Stack Overflow and saw the poster's name. It's mirrored on both x and y axis. The real name should be Chandan but actually it's this way

How is this possible?

    I'm not sure if a question about the workings of Unicode, is actually on-topic here. Commented Apr 29, 2017 at 9:34

    @NikhilAgrawal What makes you think that it shouldn't be allowed, and for what reason actually? Commented Apr 29, 2017 at 9:36

    @πάνταῥεῖ: First we are not programmed/evolved to read English that way. Second, its difficult to write that. Third, its funny and StackExchange is no place for that. Commented Apr 29, 2017 at 9:38
  • @NikhilAgrawal Nicks are just personal choice. Not much to do with putting inappropriate fun into post contents. Commented Apr 29, 2017 at 9:43
  • @NikhilAgrawal Also, you should make your question clearer about that concern. As for now you are merely asking how's that possible from a technical POV. Commented Apr 29, 2017 at 9:51
  • @πάνταῥεῖ no, he should ask another feature request question unless it has already been asked. I've answered the question he asked. Commented Apr 29, 2017 at 9:53
  • @Robert Yes you've answered the technical part, which is already off-topic here as I mentioned. Commented Apr 29, 2017 at 9:55
  • I disagree that it's off topic, but that's why more than one person is required to close/reopen questions I guess. Commented Apr 29, 2017 at 9:59

  • Amusingly - I think the question is useful so we can close other questions on this flavor of unicode abuse with this as the master question. Until The Powers that Be get fed up and we can't have nice things. Commented Apr 29, 2017 at 10:58

    Textbook example of why this should not be allowed. Commented Apr 29, 2017 at 18:52

Most (but not all) Unicode characters are allowed in user names and Unicode contains upside down and back to front versions of the Latin alphabet.

There are online converters that will take any string you type in and give you the upside down version.
