Terminal compatibility and configuration document ...

[evanpolster]

Hello,

Noob question. Not sure where to start on learning terminal emulation and its settings (or how much it is even necessary).

I have created a simple project in the PyCharm IDE and copied in the textual/docs/examples/how-to/dom4.* files into it.

When I run dom4.py from inside PyCharm its terminal emulator can decipher Unicode characters (like the icon in the Header widget).

When I run (through the same Python virtual environment) from my Gnome desktop terminal it does not decipher the Unicode character and spits out escape sequences to the terminal's stdout visible at Ctrl-C exit.

I am trying to figure out how to configure my terminal with a textual-compliant setup and I was wondering if you could help or point me to a relevant document or discussion.

Could I just double-check the output if you run the below in your terminal?

echo -e '\u2b58'

Do you know what font is being used?

[evanpolster]

When run that echo command I get a one-character white-bordered box with the hex number 2 B on the top row and 5 8 on the bottom.

I am using Source Code Pro as the font.

Hey Tom,

So I changed to use Nerd fonts Source Code Pro and it now displays the Unicode character!

Thank you,

Glad changing the font worked - I'm a bit surprised that Source Code Pro doesn't seem to support that glyph!
