Hi Stephen,
Thank you very much for replying my message.
I have done RFC testing as you suggested and yes you are right, the RFC did not pass the correct language region (should be ZH - Chinese) and when I tried to change the RFC parameter value through admin console by putting default value in the language parameter, the OrgChart still not showing the Chinese writing.
Then, I send an OSS message and they suggest to check the preference > preferences settings > languages in admin console. On the enable/disable language & set default language section, I found that only English is available, so I report back to OSS and they suggest me to install the Nakisa language pack. OSS will provide the download link for Nakisa language pack. After I install the language pack, the Chinese language is available in my Nakisa build and then I just need to re-publish the Nakisa OrgChart page and the Chinese character is now showing.
Just for your information, the Nakisa language pack is not affected the whole Nakisa build, let say you have 3 builds in your system, when you install the language pack it is not affect those 3 builds, you have to chose which build that is going to be installed. See the following scree shot.
So, make sure you re-install the language pack when you create a fresh build.
Thank you very much.
Regards,
Bobbi
