Where "icon-remove-sign" has gone in Font Awesome 4.0.3
font-awesome
Solution
It appears the icon is now called `fa-times`: http://fontawesome.io/icon/times/.
At least as I understood the changes, the names should be more consistent with the actual icon shape, and "times" is the correct name for ×.
Problem
Font Awesome has recently changed icons notation from for example `icon-shield` to `fa-shield`. But where has icon previously known as `icon-remove-sign` gone in the same time? I can't find it anywhere within Font Awesome 4.0.3 icon list. Actually I don't see anything with `remove` in name or anything that would "accompany" (as opposite) icon (now called) `fa-check`. In general, nearly every FA's "yes"-like icons have their counterparts ("no"-like icons). In general, you have variety of icon-sets for both "success" and "fail"-like situations. But this one is clearly missing.
