Description Andrei Alexandrescu 2011-11-22 09:13:42 UTC 
unittest
{
    char[] chars = ['à','è','ì'];
    assert(chars == "àèì");
}

The assertion fails for the obvious reason there's no room in chars for the multibyte characters. The initialization should not compile because it attempts to truncate wide characters into meaningless bytes.
Comment 1 Trass3r 2011-11-22 12:19:23 UTC 
It's more general:

void main()
{
	char a = 'ä'; // compiles fine
}
