A) Use tput or an ANSI library to obtain the code sequences based on the
TERM setting instead of hard coding them.

B) See vttest https://invisible-island.net/vttest/vttest.html for xterm
tests

<br>
This might be slightly off-topic.=C2=A0 I am using a tool called wp-cli, wh=
ere <br>
it tries to set &quot;bold&quot; values in its help text thusly:<br>

=C2=A0 =C2=A0wp &lt;command&gt;<br>
<br>
ESC[1mSUBCOMMANDSESC[0m<br>
<br>
So obviously, when I see those escape codes, my first thought was &quot;I&#=

running screen, it&#39;s not recognizing them&quot;.=C2=A0 But that&#39;s n=
ot it.<br>
<br>
The problem happens even outside of screen, where terminal color still <br>
works perfectly well.=C2=A0 It breaks with both iterm and the mac terminal =
app. <br>
It breaks over both mosh and ssh.<br>
<br>
Ergo, either this is some kind of a terminal issue (I&#39;ve tried xterm an=
d <br>
xterm-256color), or a bug with the script where what it thinks is an <br>
escape code actually isn&#39;t sending the right escapes.<br>
<br>
Before I report this as a bug to them, I&#39;d like to see if I can find so=
me <br>
kind of &quot;rosetta stone&quot; that outputs various things that a termin=
al should <br>
support.=C2=A0 Ascii, Colors, 256-colors, ANSI escape codes, line draw <br>
