Git: how to specify file names containing octal notation on the command line

For non-ASCII characters in file names, Git will output them in octal notation. For example:

> git ls-files
 "\337.txt"
 

If such a byte sequence does not represent a legal encoding (for the command line's current encoding), I'm not able to enter the corresponding String on command line. How can I still invoke Git commands on these files? Obviously, using the String which is displayed by git ls-files does not work:

> git rm "\337.txt"
 fatal: pathspec '337.txt' did not match any files
 

Tested on Windows, with msysgit 1.7.10 (git version 1.7.10.msysgit.1)
