Hi 

the error messages are the same on Windows XP. The problem
seems to be the type of 'w_sonderzeichen'.
If you change the type from wchar to dchar then dmd is happy
and at least on linux you see the Euro sign (on Windows console
output is not very useful).

Chears,
Sivo.

void main()

    dchar w_sonderzeichen = '\u20ac';    // Euro Zeichen

Output:
w_sonderzeichen = €

 If you change the type from wchar to dchar then dmd is happy
 and at least on linux you see the Euro sign (on Windows console
 output is not very useful).

 import std.stdio;
 
 void main()
 {
     dchar w_sonderzeichen = '\u20ac';    // Euro Zeichen
     writefln("w_sonderzeichen = %s ", w_sonderzeichen) ;
 }

 Output:
 w_sonderzeichen = €
 

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";
