I do not dispute that there may be design bugs in Windows
in this area, but the behaviour of KPSEwhich is inconsistent
with other command-level utilities.  KPSEwhich returns the
strings reported in the earlier message; DIR/S, on the other
hand, returns what one would expect with no character
substitutions :

D:\Users>dir /s Cécile.txt
 Volume in drive D is Data
 Volume Serial Number is E0B8-250B

 Directory of D:\Users\Cécile

13/04/2013  11:47                13 Cécile.txt
               1 File(s)             13 bytes

     Total Files Listed:
               1 File(s)             13 bytes
               0 Dir(s)  55,877,554,176 bytes free
