[bug#59975] [PATCH] guix: Show better progress bars.

[Julien Lepiller]

Hi Guix!

The attached patch is a small improvement on our progress bars. Instead
of our cute ASCII art:

1.2MiB/s 00:04 [###               ]  18.5%

We get something a little more smooth:

1.1MiB/s 00:04 ▕███               ▏  17.1%
1.2MiB/s 00:05 ▕███▋              ▏  20.7%

Using unicode characters that can represent 1/8 of a character width.

I used port-encoding to detect when the output supports unicode, but
maybe there's something more dedicated to figuring that out? When the
port encoding is not UTF-8, we fall back to the ASCII version.

Thoughts?
