Comment(by malcolm.wallace@…):

 I have no idea whether the following observation is relevant here or not,
 but I recently discovered that in the Windows Command Shell (DOS box, also
 used by the default Cygwin shell), even if the locale is set to C.UTF8,
 there is something weird happening such that it believes it is in a
 different encoding (one of the 8-bit non-variable-length code pages).
 Changing the font (from Raster to e.g. Lucida Console) seems to encourage
 the shell to believe the C.UTF8 encoding setting more firmly.  Alternative
 shells (such as MinTTY) are more consistent.
