Right, sorry for the misattribution. But the point stands, I think --- IPA [w] isn't just a labial approximant, so it isn't the right symbol to start from when transcribing a labial-retroflex one. I'm not sure if the US English sound in question is labiodental or bilabial, but I'm guessing the former. Perhaps not coincidentally, a voiced labiodental approximant happens to be a known idiosyncratic variant of [r\] in RP; the IPA is script v, X-SAMPA [P] or [v\]. (If bilabial is wanted, the IPA chart has an example for the lowered diacritic where a beta (voiced bilabial fricative) becomes a voiced bilabial approximant when lowered (i.e., X-SAMPA [B_o])). Of course the converter doesn't convert [P`] or [B`_o] either.

U+025A is X-SAMPA [@`] (and U+025D is X-SAMPA [3`]). When an open-mid unrounded central vowel ([3]) can be rhotacized, it should be possible to rhotacize a close-mid unrounded central vowel ([@\]) as well --- but the converter won't let us.
