Very cool domain.I've sold lots of one LETTER IDN names from as low as $50 to as high as $3000.That being said,I think this one has some decent value,probably a few hundred.
It would help to know what it's called and which (if any) keyboard this can be easily typed on.With the accented letters,9 times out of 10 they're found right on the keyboard in the country they're used in.I'm not sure about "punctuation" type symbols.
