In my mind it's defined something like this:

class Font
{
 ...

    /** Render the given code point at
        the current (x,y) cursor position. */
    void render( dchar c )
    {
        ...
    }
}

(Of course I don't know minute details like where the "cursor position"
comes from, but I figure it doesn't matter.)

I probably wrote some code like that loop a very long time ago, but I
probably don't have that code around anymore, or at least not easily
findable.
