It's normal.  xargs uses whitespace to delimit its incoming filenames.
Both find and xargs (at least in NetBSD and FreeBSD) have arguments
to help you work around this situation.  Take Simon's example:

	find . -type f -print | xargs crc-calc-program

Instead, use this:

	find . -type f -print0 | xargs -0 crc-calc-program

Find's -print0 uses a NUL character instead of a newline to delimit
its output, and xargs -0 uses a NUL instead of whitespace to delimit
its input.

Certainly I use this all the time to cope with filenames with weird
characters in them.  Of course, crc-calc-program should be able to
cope with these filenames also...

Hope this helps
