The windows console is by default adjusted to your local codepage. It
can be set to be utf8 with the shell command "chcp 65001" or your
program can do that with "SetConsoleCP( CP_UTF8 );"
In Tango programs this is done by default, afaik.
The compile errors you see seems like a implementation bug in phobos to me.
You can also use char[] instead of dchar,
char[] w_sonderzeichen = "\u20ac";
