Hi,
The scenario is, there's an backend OSGI service which reads some data from
a csv file and sends it to the jaggery. The csv file can contain characters
in different languages as well, hence it is read with UTF-8 character
encoding. When I try to assign the data received from the osgi service to
the Jaggery response variable, it throws out the following exception saying
certain characters are not ISO 8859-1 encoded.

Error is thrown from the 3rd line of follow. Please refer the attached file
for the complete error log.

Here 'json' is the data received from the backend service.
However, this occurs when the csv file contains some Chinese/Latin
characters and is read as UTF-8. But if the file is read as ISO-8859-1 and
send to Jaggery, it works.
Does Jaggery always use the ISO-8859-1 encoding?
Thanks,
