Thank you Otto,
For solving my CRI! I missed that in man bash, but I knew I had to
quote the escape sequence. It was a forest for the trees issue. Also,
single quotes work just fine as well.
The error is really weird. It was the result of the 'echo *' statement.
Why it would interpret the *** is also just as strange.

man bash (line 2988)
echo [-neE] [arg ...] Output the args, separated by spaces,
followed by a newline. The return status is always 0. If -n is
specified, the trailing newline is suppressed. If the -e option is
given, interpretation of the following backslash-escaped characters is
enabled. The -E option disables the interpretation of these escape
characters, even on systems where they are interpreted by default. The
xpg_echo shell option may be used to dynamically determine whether or
not echo expands these escape characters by default. echo does not
interpret -- to mean the end of options. echo interprets the following
escape sequences:
\a alert (bell)
\b backspace
\c suppress trailing newline
\e an escape character
\f form feed
\n new line
\r carriage return
\t horizontal tab
\v vertical tab
\\ backslash
\0nnn the eight-bit character whose value is the octal
value nnn (zero to three octal digits)
\xHH the eight-bit character whose value is the
hexadecimal value HH (one or two hex digits)
