I already do this, everything in my media is extremely cleanly named because they are handled by sonarr

series name/season 00/EPSxxExx-“episode title”

so it’s not a file format issue. It gets a lot of them but there are certain things especially if they are recently aired or currently airing where it will simply fail to find a match until I give it the Japanese name at which point it manages to find the metadata for the English name. Really stupid stuff like that
