This was the second bug reported in bug 8601. It's completely unrelated to the
first one. A string initialized with an array literal doesn't
support ~= of a character of a larger size.

bool bug()
{
    string r =  ['x', 'q'];
    dchar c = 'ü';
    r ~= c;
    assert(r == "xqü");
    return true;
}

static assert(bug());

bug.d(8): Error: Cannot interpret r ~= c at compile time

I'm not entirely sure what to do with this. The problem is, after r~=c, is r a
string literal or an array literal?
