New comment by qsuscs on mblaze repository https://github.com/leahneukirchen/mblaze/issues/146#issuecomment-504772957 Comment: I just realized that as of commit 6710fd9 (which is older than this issue), this should not happen. Unless one uses filters: in that case, mshow does not convert its output to UTF-8. So indeed, when one uses e. g. mflow as filter for text/plain, mrecode should be added to the filter chain. I’m not sure whether mshow _should_ behave this way, but it does, anyway.
