  The "Encoded attribute" data is just printed to a string.  See https://github.com/FreeRADIUS/freeradius-server/blob/v3.2.x/src/modules/rlm_rest/rest.c#L800

  Perhaps the locale for the system is not Korean?

  FreeRADIUS doesn't convert strings to ISO-8859.  It just prints the data to create JSON.

  So something on your local system is deciding that UTF-8 text is wrong, and is converting it to ISO-8859.  

  There's no automatic conversion in the REST module, so it can't be that.
