It doesn't require any new api:
(inh,outh,errh,pid) <- runInteractiveProcess path args Nothing Nothing
-- We want to process the output as text.
hSetBinaryMode outh False
As of a couple weeks ago the docs for runInteractiveProcess even say:
-- The 'Handle's are initially in binary mode; if you need them to be
-- in text mode then use 'hSetBinaryMode'.
