When we try to update the profile fields like middle name via API with japanese charcters, the values are stored as junk characters, but the same is working if we do the update directly on the adobe campaign standard profile page manually.
Any pointer to fix this will help us more.
Thanks in advance.
For sending special characters, you need to send the right content type in the HTTP header:
Content-type: application/json; charset=utf-8
in your load file activity change the file format ->encoding to utf-8 while importing profiles.
