> Result is always this:
> getlocale: (None, None)
> getdefaultlocale(): ('en_US', 'UTF-8')
> fs_encoding: UTF-8
> sys default encoding: ascii
> Setting the following variables in /etc/sysconfig/httpd and restart as

> export LANG="en_US.UTF-8"
> export LC_ALL="en_US.UTF-8"
> does not change anything in particular the system default encoding which
> is the reason why the upload is failing.
> Adding such variables to WSGIDaemonProcess:
> WSGIDaemonProcess geonode lang='en_US.UTF-8' locale='en_US.UTF-8'
> python-path=/home/geonode/geonode:/home/geonode/.venvs/
> geonode/lib/python2.7/site-packages user=apache threads=15 processes=2
> just affects the getlocale() function while default encoding is unaltered.
> The only way to affect it would be to add and enforce it:
> import sys
> reload(sys)
> sys.setdefaultencoding('utf-8
