I think that as your object is emoji drawing, not mathematics, this request can't be justified that way.
Maybe it would make more sense to try and check whether modification combining characters to shift the change the combined character into other weight/decoration/color and/or other character effects could be built, that could be used not only along emoji, but with all other characters. Currently those transforms require the use of another text protocol, like HTML, or ANSI sequences for terminal, or even proprietary and add-hoc text file structures like Microsoft's .doc and .rtf (and other not that proprietary, but equally dependant on specific software to be proper rendered, like .ooxml and .odf). Since modificator characters for color and others have been tried and tested in Unicode land for some emojis, the ball to have in-unicode proper character transforms could start to roll - Does anyone know if there is already an initiative like that? I'd like to know more about it. (as for the O.P.: I think the way out for you now is to use an out-of-unicode markup to select a heavier-looking font for the `+` and `=` characters) js -><- On Wed, 18 Dec 2019 at 09:42, Marius Spix via Unicode <unicode@unicode.org> wrote: > Unicode has a HEAVY PLUS SIGN (U+2795) and a HEAVY MINUS SIGN (U+2796). > I wonder, if a HEAVY EQUALS SIGN could complete that character set. > This would allow emoji phrases like 🐈 ➕👨= ❤️.
