AFAIU, coding category is not used for font selection, it is used to narrow 
down appropriate coding systems when a buffer has the coding system 
"undecided".  Since this character is covered by the JISX-0208 standard, it 
gets the Japanese tag (along with most ASCII characters and many more that you 
might not consider Japanese).
