IBM's backup software TSM/Spectrum Protect messes this up as well.
If the machine has a UTF-8 encoding (like, say, every modern system), it will try to treat filenames as valid UTF-8 strings and fail to back up files which don't fulfill that assumption. The "solution" is to run the TSM software with a single-byte locale like en_US.
I've seen a number of shops that were silently missing files from backup from old systems because of this problem.
