Just upgraded to 0.9.19 and bug still persists. Window size is 131 * 41.

This isn't a issue caused by bashtop, but by the terminal you are using. Make a bug report that some symbols aren't rendered correctly with the creator of the terminal.

turkeyphant commented 4 years ago

Which symbols are being rendered incorrectly so I can report this?

aristocratos commented 4 years ago

Also needs a UTF8 locale and a font that covers:

Unicode Block “Braille Patterns” U+2800 - U+28FF
Unicode Block “Geometric Shapes” U+25A0 - U+25FF
Unicode Block "Box Drawing" and "Block Elements" U+2500 - U+259F

Looks to be the "Braille Patterns" block that's not being rendered at a uniform width.

@turkeyphant I don't think that font is at fault here since it works fine in a regular terminal. I think the issue is with the terminal itself:

Terminal used: Secure Shell App

It seems the font doesn't contain the glyphs so it's the fallback font that doesn't have uniform width glyphs. I'd tried every font available including Cousine, Inconsolata, Roboto Mono, Menlo, etc. and all have the same issue.

I'm not sure if it's all the fonts at issue but would it be possible to have an option to use alternative glyphs that are more widely supported?

aristocratos commented 4 years ago

Since the symbols of the fallback font is correct it's far more likely it's the terminal that hasn't got proper wide character support.

And I'm not gonna spend time coding to accommodate for bugs in other software, especially when I don't even know which symbols would render correctly.

The way I see it you got 4 alternatives:

  1. Read through the documentation for hterm and see if you can find any special options for font rendering that could help you.
  2. Report the bug and get support for the issue at https://bugs.chromium.org/p/chromium/issues/list?can=2&q=component%3APlatform%3EApps%3EDefault%3EHterm
  3. Use another terminal emulator.
  4. Use another resource monitor.

Fair enough.

I will reopen this to bring attention to it in the hopes somebody else has a solution.

And I would urge you to share if you find a solution.
