Seeing your `<heart>' got me thinking. If there's expansions for U+2661 `white heart suit', or U+2665 `black heart suit', etc., then they're `H'. An emoji heart would be `<heart>', but there doesn't seem to be a simple plain obvious heart emoji, but dozens. :-) > > Because it's a recent invention and someone just copied the ISO > > 4127.

No, I agree, they wouldn't. But few will see it? ASCII and ISO 8859-1 readers? ISO 8859-15 has a `€' as 0xa4. Is -15 becoming more common, replacing -1? https://en.wikipedia.org/wiki/ISO/IEC_8859-15 `\z-E' or `\z=E' seems to give a reasonable approximation here and it does follow tty-char.tmac's These definitions are chosen so that, as far as possible, they: ... - represent the character's graphical shape (not its meaning) `\z=C' would be better, but the above comment also says - work on devices that display only the last overstruck character as well as on devices that support overstriking I suspect context would help make the meaning more clear, and the single column valuable. > Anyway, changing this wasn't part of the proposed patch in the first > place. :-) No, you're quite right. I wonder if John Gardner's HTML-canvas renderer could lay down text in a dark grey that's additive to what's already there, thus over-striking would have an effect, e.g. `\z~o' as well as bold. For plus points, every glyph placed could have a slight random `jitter' applied to both its coordinates so bold was also thicker, except around the edges. Half-line motions would be nice too, John. ;-) -- Cheers, Ralph. https://plus.google.com/+RalphCorderoy
