In the perl script, both "-k" and "-K" options _assign_ the $preconv variable (which ultimately gets passed to groff), so the second overwrites the first, leading to the encoding info "utf8" getting lost. However, "-Kutf8 -k" feels unnatural to me, whereas "-k -Kutf8" feels reasonable. If pdfmom was only tested with the latter order of options, it would not have been noticed that "-k" got lost, because it would be implied by groff seeing "-K". I guess the simplest fix would be to have pdfmom _append_ the "-k" and "-K" options to $preconv, i.e., replacing $preconv=$c; by $preconv.=' '.$c; at all three occurrences (the space makes sure the option strings don't run together). But I have very little experience with perl, perhaps a cleaner solution exists.
