It was my understanding that using 'single quotes' meant that I didn't have to
worry about it being escaped by the shell? The above is shown literally on
Debian/etch.

I think that is a Dash nasty? Surely this is messing up someone's regex scripts
somewhere, and it doesn't smell much like a Bashism.

$ bash
$ echo '\\'
\\
$ dash
$ echo '\\'
\

Is the practical solution to bypass the issue by using "double quotes" and
explicitly double-\\ any intended \\s?

Debian/etch.

It isn't the shell; it's "echo" that's the problem.

Whether or not the "echo" command interprets escape sequences by
default varies between implementations.

In particular, the GNU version (both the bash built-in and the
standalone echo program from coreutils) does not conform to the Single
Unix Specification.

The SUS interface doesn't support any options, and escape sequences
are always enabled, while the bash version requires that you use -e to
enable them.

POSIX simply states the the behaviour is implementation-defined if any
argument contains a backslash.

$ bash
$ echo '\\'
\\
$ dash
$ echo '\\'
\

No. If you want to use a backslash, you'll need to forego "echo" in
favour of e.g. a here document:

cat <<EOF
          __________ ___ __________ _______________
         / ____/ __ \/ | / ___/ ___/ / ____/ _/ ___/
        / / __/ /_/ / /| | \__ \\\\_ \\ / / __ / / \\__ \\
       / /_/ / _, _/ ___ |___/ /__/ / / /_/ // / ___/ /
       \____/_/ |_/_/ |_/____/____/ \____/___//____/

EOF
