Q2. Why does the screen width not function correctly when non-printing characters are in my prompt?
A2. The shell computes the screen width by subtracting the width of the prompt from the screen width. To account for non-printing characters, for example escape sequences that display in the title bar, follow these characters with a carriage return. The shell starts recomputing the width after each carriage return.
In your case, you will need to figure out how many of your characters are non-printing and inbed a c/r at the right point to correct the calculation of characters remaining on the line.

ASA(1) BSD General Commands Manual ASA(1)
NAME
asa -- interpret carriage-control characters
SYNOPSIS
asa [file ...]
DESCRIPTION
The asa utility reads files sequentially, mapping FORTRAN carriage-control characters to line-printer control sequences, and writes them to
the standard output.
The first character of each line is interpreted as a carriage-control character. The following characters are interpreted as follows:
<space> Output the rest of the line without change.
0 Output a <newline> character before printing the rest of the line.
1 Output a <formfeed> character before printing the rest of the line.
+ The trailing <newline> of the previous line is replaced by a <carriage-return> before printing the rest of the line.
Lines beginning with characters other than the above are treated as if they begin with <space>.
EXIT STATUS
The asa utility exits 0 on success, and >0 if an error occurs.
EXAMPLES
To view a file containing the output of a FORTRAN program:
asa file
To format the output of a FORTRAN program and redirect it to a line-printer:
a.out | asa | lpr
SEE ALSO
f77(1)
STANDARDS
The asa utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
