pgAdmin 4 commit: Better handling the non-ascii characters for differen

Better handling the non-ascii characters for different database objects.

Using 'psycopg2.extensions.UNICODE' (for Python < 3) in the psycopg2
driver for proper conversation of unicode characters. Also - adjusted
the string typecaster to take care of different character types (char,
character, text, name, character varying, and their array types).
