Emoji don't always render: please prefer ASCII or limited Unicode.

[pnathan]

Describe the bug
What is the emoji? I just see boxes on my terminal.

To Reproduce

Steps to reproduce the behavior:
Run the tool on Konsole on Linux

Expected behavior
Colorized output or non-emoji textual output.

Screenshots

Versions (please complete the following information):

• OS: Linux, Terminal is Konsole on KDE5
• Popeye 0.1.4
• K8s: 1.9.6 for this cluster

Additional context

This is both a cross-platform and an accessibility issue.

Note - I can submit a PR that looks like

but I suspect that an "emoji-on/-off" flag would be preferred, yes?

@pnathan Thank you for this report! I think scanning the user env vs flags might be a better approach to this. Thus tuning the sanitizer down based on the capabilities of the terminal.

@derailed spent a few minutes rummaging about. It looks like this is partially dependent on rendering engine (terminal emulator) and font, which is annoying. One trick suggested here is - https://stackoverflow.com/a/44445547 - I copypasted from my terminal to run it -

echo -n 🔊 | wc -m

but that simply returns one, just like echo -n w | wc -m does. So that seems to be a wash (-m returns number of characters: an emoji should be one character, regardless of byte length, just like, e.g., a kanji. So that seems to be a poor mechanism of assessing anyway).

It might be that switching on the environment variable TERM is the proper thing to do:

emacs-shell gives dumb and my Konsole terminal gives xterm-256color.

This is probably a minefield of "switch case", but plausibly it might work.

Contemplating, it might be that the proper thing to do would look a lot like ls --color

      --color[=WHEN]         colorize the output; WHEN can be 'always' (default
                               if omitted), 'auto', or 'never'; more info below

where auto tries to figure itself out, never, and always can be specified.

@pnathan Thank you so much for your investigation and report! I'll take a look at this on the next drop and see if we can figure out a way to compliment the various terminals in the report.

@pnathan I've added a flag in 0.2.0 -j or --jurassic based on some of your recommendations, hopefully that will help some... Thank you!
