faust Allow suppression of info characters when log level set to warn

Checklist

[x ] I have included information about relevant versions
[ x] I have verified that the issue persists when using the master branch of Faust.

Steps to reproduce

Run a worker with -l warn

Expected behavior

Only print warning and above

Actual behavior

Rather than suppress the entire output of info, it appears to print a <?> character (which I think represents a 😊)

Mind providing an example? A lot of logging done in Faust is controlled by mode-streaming, see https://github.com/faust-streaming/mode/issues/36 for an example of how a lot of logging is controlled by Mode.

An image possibly shows the best example, but I'll also include a copied trace below:

This happens for me with every faust application i have. I assume it's a faust print out, not kafka, or aiokafka related.

The info ones here are deliberately turned on for debugging that worker, but I'm starting multiple workers in a single terminal. I can't imagine that's an issue. When all are set to -l info I basically get the familiar start up table for Faust applications, but a stack of these � icons. On a different machine (centos 8 stream), I get a series of interesting icons:

I was reading through documentation and I came across this: https://faust-streaming.github.io/faust/reference/faust.utils.terminal.spinners.html

I've never seen a spinner before in logs, but it looks like it's producing the patterns you see here, somehow. No other library that is a dependency of Faust, as far as I know, produces such an eccentric behavior.
