 Here is Toyoko Inn in Seoul.  There are many of these hotels in Korea and
 Japan.

 http://www.openstreetmap.org/browse/node/871717853

 Nominatim search for "Toyoko Inn, Seoul" is great!  "Toyoko Inn, Busan" or
 "Toyoko Inn, Tokyo" works as expected too.

 "東横イン", which is Japanese for "Toyoko Inn", seems to work.  I get some
 useful results.
 "토요코인", which is Korean for "Toyoko Inn", does not work.  I get no
 results, but I know this string is in the name=* field.

 Please tell me if this is a bug, or if there is a problem with the data.
 If it's a bug, please mark it as a 'to do'.  If it's a problem with the
 data, please explain how to do it properly and I will re-do all Toyoko Inn
 hotels in Korea (there are about 8 of them).

 I have had success searching for other Korean text.  For example, "중앙로" or
 "Jungang-ro", which means "Central Street", will give some results.

 Thank you.
