Unicode issue with Database Names

[stairsdba]

Thank you for the excellent plugin. I have been having problems with Zabbix 3.4 and the plugin where the database discovery is returning error

Value should be a JSON object.

When I run the command manually I get output like the following

root@XXXX bin]# zabbix-mongodb.py

• mongodb.discovery {'data': [{'{#MONGODBNAME}': u'admin'}, {'{#MONGODBNAME}': u'db1'}]}
• mongodb.ismaster 1

The u for unicode data seems to be causing problems with Zabbix monitoring.

Thanks
