ANSI test scripts to test terminal capabilities?

Hey there all,

This might be slightly off-topic.  I am using a tool called wp-cli, where 
it tries to set "bold" values in its help text thusly:

ESC[1mNAMEESC[0m

   wp

ESC[1mDESCRIPTIONESC[0m

   Manage WordPress through the command-line.

ESC[1mSYNOPSISESC[0m

   wp <command>

ESC[1mSUBCOMMANDSESC[0m

So obviously, when I see those escape codes, my first thought was "I'm 
running screen, it's not recognizing them".  But that's not it.

The problem happens even outside of screen, where terminal color still 
works perfectly well.  It breaks with both iterm and the mac terminal app. 
It breaks over both mosh and ssh.

Ergo, either this is some kind of a terminal issue (I've tried xterm and 
xterm-256color), or a bug with the script where what it thinks is an 
escape code actually isn't sending the right escapes.

Before I report this as a bug to them, I'd like to see if I can find some 
kind of "rosetta stone" that outputs various things that a terminal should 
support.  Ascii, Colors, 256-colors, ANSI escape codes, line draw 
characters, emojii, etc.

I've found https://gist.github.com/sdeaton2/8450564 but I'm looking for 
something more complete.

Does anyone know of such a thing?
