rdiff-backup using escape codes on vfat thumbdrive

I thought it may be nice to use rdiff-backup to backup my websites to a thumb drive. But all the capital letters are substituted with octal escape codes. How can I over come this?

There are no issues backing up to another ext3 drive.

The source drive is ext3 the thumb drive is vfat mounted as:

/dev/sdd1	/media/thumbdrive vfat rw,nosuid,uid=1000,gid=1000,umask=000 0 0

Example:
original - SOLMETRA-FlashUploader_102
becomes - ;083;079;076;077;069;084;082;065-;070lash;085ploader_102

rdiff-backup -V
rdiff-backup 1.2.7

rdiff-backup command:

rdiff-backup --exclude-symbolic-links --terminal-verbosity 5 --include-globbing-filelist /home/mike/.rdiff-backup/sys_files / /media/thumbdrive/www

Ubuntu version 2.6.28-15-generic #52-Ubuntu

Still need help --override-chars-to-quote turns all directory and file names to octals. --override-chars-to-quote made it worse
