In D char literals as 'x' or even string literals as "xx" are 
seen as instances of all the types of strings and chars, it's not 
a bug, it's a feature:

void main() {
     char x1  = 'x';
     wchar x2 = 'x';
     dchar x3 = 'x';
     string s1  = "xx";
     wstring s2 = "xx";
     dstring s3 = "xx";
}


There is a way to specify the type of a string, so this gives 
errors:

void main() {
     string s1  = "xx"d;
     string s2  = "xx"w;
     wstring s3 = "xx"d;
}
