Deleting filenames that have space and special cha

Question

I have a large filelist of 7000+ files to delete from a Unix directory. I could have accomplished this using a while loop

while read file
do
rm $file
done < filelist

or just

cat filelist | xargs rm 

The challenge comes from deleting those files which have "Windows-like back slash \, colon : and spaces " in their filenames.

Eg.
C:\Sxxx Accr Vac 1111.txt
N:\Lxxx\Dxxx_FOLDER\Mxxx\Mxxx_DOWNLOAD_TEXTFILE_PATH\000000_Mxxx_Bxxx-Pxxx-H.txt
N:\Lxxx\Dxxx_FOLDER\Mxxx\Mxxx_DOWNLOAD_TEXTFILE_PATH\130607_Mxxx_Bxxx-Cxxx-L.txt
N:\Lxxx\Dxxx_FOLDER\Mxxx\Mxxx_DOWNLOAD_TEXTFILE_PATH\140103_Mxxx_Xxxx-Pxx-H.txt

To delete these, I had to enclose the entire filename in double quotes. I wanted to preview the rm commands for each file before actual deletion:

while read -r file
do
echo rm \"$file\"
done < filelist

The problem is that filenames with "\0000" in their strings

eg. N:\Lxxx\Dxxx_FOLDER\Mxxx\Mxxx_DOWNLOAD_TEXTFILE_PATH\000000_Mxxx_Bxxx-Pxxx-H.txt

always ended up with the "\0000" mysteriously truncated from the output.

Eg. For the above file, the rm commands shows up as:
rm "N:\Lxxx\Dxxx_FOLDER\Mxxx\Mxxx_DOWNLOAD_TEXTFILE_PATH00_Mxxx_Bxxx-Pxxx-H.txt"

None of the other files had this problem after passing through the loop.

Any clues?
