The problem is that you can't put quoted strings inside variables and expect them to get split sanely AFTER substitution has already happened. It'll split apart on spaces but not much else. It doesn't re-check for quoted strings etc. after substitution's already happened. So your script isn't being given **, it's being given '**', quotes and all! And yet, if you remove the quotes, it WILL substitute for *, even though it doesn't substitute for strings...
Put them in an array so there's no guessing at all involved in which parts are string, which parts are quotes, and where it should split them apart; it'll do so just like you'd expect of program arguments. There's a magic syntax to spit out an entire array as properly separated parameters too.
This won't work in ordinary sh, which doesn't have arrays.

So I understand that I should be able to ouput a literal \ by escaping it with a preceding \. My problem is that I am trying to ouput a script that will subsequently be run on a different system with UNC pathing, so I want to ouput two \\ in a row, but escaping them both in sequential order is not...

ppmtosixel(1) General Commands Manual ppmtosixel(1)NAME
ppmtosixel - convert a portable pixmap into DEC sixel format
SYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC
LJ250 color inkjet printer.
If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table
begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file.
OPTIONS -raw If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to com-
pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magni-
tude larger than a compressed file and prints much slower.
-margin
If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is speci-
fied, a 1.5 inch left margin will offset the image.
PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?.
BUGS
Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion. If the original PPM maxval was
greater than 100, rescaling also reduces the image depth. While the actual RGB values from the ppm file are more or less retained, the
color palette of the LJ250 may not match the colors on your screen. This seems to be a printer limitation.
