Betting on the citation Gönen M, Heller G (2005) in man/mlr_measures_surv.cindex.Rd which stems from bibentries.R where the Umlaut is properly unicode escaped already as G\u00f6nen.

I assume it's escaped correctly in R but then written to Rd unescaped.
Easiest way to circumvent this would be to use the oe -> Goenen workaround I guess.
