Re: Pgadmin4: emoji in comments - Mailing list pgadmin-hackers

Hi,

This seems to issue with psycopg2. (https://github.com/psycopg/psycopg2/issues/331)

To resolve this issue we have two solutions,

Solution-1

we can upgrade the psycopg2 module to newer version 

Solution-2

Re-write of our 'qtLiteral' implementation which also accepts current connection object as parameter and using that we can prepare "adapt" for encoding used by current connection but this will affects almost every module (sql template related changes).

Regards,

Murtuza

You seem to have posted on -hackers, though I had to approve it :-)

The bug tracker can be found here:
https://redmine.postgresql.org/projects/pgadmin4/issues

I'll log this one for now - thanks!
