🆖 Squared NG

The letters NG, shown enclosed in a square, which are an acronym for the words No Good.

The origin of NG refers to bloopers shown during or after the credits of a live television show in Japan (known as NGs), but can be used in any field as a form of shorthand for no good.

Squared NG was approved as part of Unicode 6.0 in 2010.
