Welcome to the happy world of unicode then...I'm guessing your c library normalizes text (which is
probably not a bug...dc++ just doesn't consider those aspects of unicode).

The ADC spec says filenames are case insensitive, hence the lowercase (otherwise they'd require case
insensitive matching which is just as tricky). I'm guessing the lowercase call on xml load is for
backwards compatibility.
