I vaguely recall when we were discussing these particular symbols that there was some verbiage about Unicode encoding text and "notational systems," and one of us brought up that it could be argued that schematic symbols are a "notational system." However, this was a very minor theoretical point; no one has attempted such an argument and that was not the argument we were making. As far as this goes in practice "notational systems" seems limited to things like phonetic transcription, chess notation, sheet music, and other things that are at least vaguely text-like, as opposed to a fully two-dimensional diagram like an electronic schematic.</div><div><br></div><div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature">-- Rebecca Bettencourt</div></div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Aug 13, 2024 at 1:20 PM Martin Vahi via Unicode <<a href="mailto:unicode@corp.unicode.org" target="_blank">unicode@corp.unicode.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><br>
Dear readers of this list,<br>
<br>
I know that there is literally a shit emoji character, but when I tried<br>
to find characters for electronic components like diodes, capacitors,<br>
resistors, radio lamps, etc. then I failed to find any. The same with<br>
XOR gate, OR gate, AND gate, MUX, DEMUX, etc.<br>
<br>
Even ASCII had special characters for drawing the DOS era windows in<br>
console, so a wish for some characters that at least in some combined<br>
manner would allow to draw electrical schematics in console windows<br>
does not look too extreme to me. Some reference to some mail archive,<br>
where that topic has been discussed in the past, would be helpful.<br>
<br>
As a side-note, some modern era Linux terminals allow to display<br>
graphics, even videos, in pixel analogues called sixels.<br>
I even have a YouTube demo video about that:<br>
