[PATCH] Fail softly if file system does not like test data.

Most unix file system allow almost any byte sequence, but other may reject
sequences that are not valid according to the locale. This change makes
failure somewhat less likely by using UTF-8-encoded characters (which
happen to be valid interpreted as ISO-8859-1 and skips the test if the 
local file system does not support the test data.

Please try this on cygwin (western iso-8859-X, korean on FAT & NTFS) and 
MacOSX (HFS) where we know there was a problem. The non-ascii filename
test should be skipped, with a notice) in most asian locales on Windows
and MacOSX.
