Subj : console.strlen(text) vs. strip_ctrl(text).length

Hi DM,

While working on one of my scripts, there are some places where I need to get
the length of a string as it will appear on the screen.  It seems there are two
ways to do so - console.strlen(text) and strip_ctrl(text).length.  While
working on one of my JS scripts, I noticed I'm getting two different results
from each of those ways of getting string length for one of my script's
strings.  Specifically, my string has a 4 special characters to represent
arrows, which are counted by console.strlen(), but those special arrow
characters seem to be removed by strip_ctrl().  The following image shows the
text line output from my script with the 4 arrow characters (it's a help line
showing some valid key commands):

The length returned by console.strlen() is 79, whereas the length returned by
strip_ctrl(text).length is 75.

The documentation says console.strlen() will exclude Ctrl-A codes, while
strip_ctrl() removes control characters.  It sounds like strip_ctrl() might be
removing all control characters (not just Ctrl-A characters), is that correct?
I was curious if what I'm seeing is the expected behavior.
