Glyph Support Request: U+2295 CIRCLED PLUS / U+2297 CIRCLED TIMES / U+208B SUBSCRIPT MINUS

[Holzhaus]

In order to use this font for drawing diagrams of digital circuits, it would be great if you could add support for some glyphs:

Codepoint	Usage
U+2295 CIRCLED PLUS	XOR gate
U+2297 CIRCLED TIMES	AND gate
U+208B SUBSCRIPT MINUS	Indices (in this case for bits)

Example: LFSR diagram

Vim (using Fira Code)

Rustdoc (using Source code Pro)

Plain text version

This may also look broken depending on your browser font:

    ┌─────┐           ┌───┐  ┌───┐  ┌───┐  ┌───┐
┌──▶│ sₐ₋₁├┬──▶ ... ─▶│ s₃├┬▶│ s₂├┬▶│ s₁├┬▶│ s₀├┬───▶ output bit

This character is not supported in SCP, what you are seeing is font fallback (I’m really wondering why code editors would choose to fall back to a different-pitch font?) In your diagram, I see a few other characters that are not supported by SCP, such as ⦻ (U+29BB) – if that is it.

Please edit your issue to make it a glyph support request, perhaps describing some usage scenario for which other yet unsupported character may be needed. (those diagrams look interesting!) Thanks!

Ah ok. To elaborate, the screenshot at the top is actually not a code editor, it's the HTML documentation generated by rustdoc, so it's the browser that messes up here :D

I'll edit the description. Thanks!

Yeah, sorry about that. It is a known bug in chromium: https://bugs.chromium.org/p/chromium/issues/detail?id=807361#c_ts1600152903

Also see my comment in the other related issue https://bugs.chromium.org/p/chromium/issues/detail?id=1083930#c10

You should set some other font like PragmataPro.
