tried to but failed

downloaded dmd-master.zip (from github)
downloaded dmd.2.063.2.zip

buidl dmd-master with vs2010
copied the produces dmd_msc.exe to dmd.2.063.2\dmd2\windows\bin

dmd.2.063.2\dmd2\src\phobos>..\..\windows\bin\dmd.exe std\algorithm 
-unittest -main

gives

Error: cannot read file ûmain.d (what is this "û" in front of main.d?)

dmd.2.063.2\dmd2\src\phobos>..\..\windows\bin\dmd_msc.exe std\algorithm

and a compiler crash


my former benchmark where done the same way and it worked without any
