Proposal to add the group mark character to Unicode
The group mark character is part of the character set (BCD Interchange Code) used by the IBM 1401 and other computers.

Adding the group mark to Unicode would make discussion of the group mark in text easier, for example in email or web pages.
The group mark looks like this:
The full proposal is in proposal.pdf. A sample font with the group mark symbol is GroupMark.ttf, with the group mark at U+E000. A demo of the group mark displayed in HTML via a webfont is here.
The proposal has been submitted to the Unicode committee for review as document L2/15-083
The proposal has been approved for addition to Unicode (minutes)
