The comment at Sum of strings without converting displays strangely on Firefox 33.1 on OSX 10.9.5. Look at the numeral 1 inside the parens in each_cons(10).

Any idea why?

What is that character that got in there?

  • \$\begingroup\$ not Chrome. Yes in FF34. It's actually not a bug, though... it's an extra character that I can't seem to find anywhere else. Maybe this is a Mozilla bug. I'll turn this into discussion \$\endgroup\$ Dec 4, 2014 at 18:05

Let's take a look at the HTML:


As you can see, a ‌​ was automatically inserted by the Stack Exchange software. This has been reported on The Mother Meta (and the reason was provided by @TimStone in the comments on that question).

Seeing as I don't see the symbol on Chromium or Firefox on Ubuntu or the app on Android, it's probably a font problem.

As further evidence, the comment I've posted below should have the same strange character in it for you.

  • \$\begingroup\$ or "Doorknob 嚏" more likely (sneeze, not flower)? \$\endgroup\$ Dec 4, 2014 at 20:43
  • \$\begingroup\$ Now I feel you are more like "Doorknob 霜" (a kind of 冰). \$\endgroup\$
