The UTC is considering a proposal to extend the types of flags which can be reliably represented by certain sequences of Unicode characters. In addition to the current mechanism using pairs of regional indicator symbols—already widely implemented—the proposal would use sequences of the TAG characters in the range U+E0030..U+E005A to represent other types of flags. The proposal also provides guidelines to specify valid sequences of TAG characters and how to interpret them. Full details of the proposal are provided in the background document.
The UTC welcomes feedback on this proposed new mechanism. Feedback could consist of an indication of support or opposition to the proposal, with reasons why, or could consist of suggestions for improvement of the proposal.
