cp files containing \ from a script

cp files containing \ from a script
I am using a sh shell to try and create a script to remove backslashes (and other characters) from filenames.
At the end of the script I need to copy the original filename (with the backslash) to the new file name.
So far I have not been able to figure out how to do that from inside a for loop.
Example:
On the command line or inside the script, I can use this "exact" command to copy the file junk/junk.txt to junkjunk.txt
cp junk\\junk.txt junkjunk.txt
and it works perfectly.
But I need to use a variable or perhaps command substitution to represent the original filename inside the script, like this:
cp "$oldfilename" $newfilename
Even though I can create a variable, that echo "$oldfilename" shows contains junk\\junk.txt -- I can not get the cp command to work.
I have tried many variations of this using multiple backslashes with no success.
Is this even possible?
Thanks in advance.....

script - make record of a terminal session SYNOPSIS
script [-a] [filename] DESCRIPTION
The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the record is saved in the file typescript. See WARNINGS. The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends when the forked shell exits or when Control-d is typed. OPTIONS
The following option is supported: -a Appends the session record to filename, rather than overwriting it. NOTES
script places everything that appears on the screen in filename, including prompts. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ |CSI |Enabled | +-----------------------------+-----------------------------+ SEE ALSO

script can pose a security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a privileged user, that is, root. Be sure that typescript is not a link before running script. SunOS 5.10 30 Jan 2004 script(1)
