Data seems to be the same, function behaviour is what seems different.

testµinto TESTµ) 

Maybe because unicode has GREEK CAPITAL LETTER MU ( 924, which looks
like capital M ), GREEK SMALL LETTER MU ( 956 ) and MICRO SIGN ( 181,
which looks like small mu ) while windows-1252 only has 0xB6 as micro.
OTOH Windows-1253 ( greek ansi ) has all three.

If your small mu are really micro-sign ( which is suspected if youused
1252 ) maybe changing them to that helps ( but I do not have the
resources to test that on hand ).
