This output is full of (probably fancy, just that I do not see them) UTF-8 characters. Even the half-sized capitals (for example Fᴇᴇ ʀᴀᴛᴇ) are printed as question-marks in my terminal (rxvt-unicode using Terminus font).

I think it would be a big help if there was an --ascii option, even better if ASCII output was the default and there was a --fancy option… What do you think @shesek ? Thank you for this amazing tool! It works very welly. This is just a way to say someone else uses it :)

[jsarenik]

F of Fᴇᴇ ʀᴀᴛᴇ is printed correctly of course. It is a common capital letter F with equivalent representation both in ASCII and UTF-8.

Thanks for the suggestion! I will look into making an ASCII-only version of the banner.

In the meanwhile, if you find the broken characters annoying, you can turn it off entirely using --no-startup-banner.

I actually like the banner! :-) Just wondering how to make it more readable in constrained environments… שבוע טוב!
