I think it’s probably common sense why we would want or need a currency symbol for the lovelace. I have only found one other proposal on this forum, I don’t know if there are others floating in the ether. I also don’t know if McCann is still in the picture and are planning to make a proposal along these lines. However, I would like to get this idea out of my head on to the screen to share with you all and ask for your feedback:
The goal would not be to design a “logo” but a glyph/symbol instead that can be submitted to The Unicode Consortium and then can be adapted to different fonts by typographers.
