# Does anyone know why there's a weird symbol in place of the 1 in this comment?

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?

• no-repro. Try in Chrome. – John Dvorak Dec 4 '14 at 17:25
• 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 – Not that Charles Dec 4 '14 at 18:05

Let's take a look at the HTML:

As you can see, a &zwnj;&#8203; 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.

• Planning on becoming "Doorknob 花" in the Spring? – Not that Charles Dec 4 '14 at 20:40
• or "Doorknob 嚏" more likely (sneeze, not flower)? – Not that Charles Dec 4 '14 at 20:43
• Now I feel you are more like "Doorknob 霜" (a kind of 冰). – jimmy23013 Dec 5 '14 at 2:19
