Incompatible character encodings: ASCII-8BIT and UTF-8

[meap]

After upgrade to latest ruby-pg 1.20, I am encountering with the following error:

Encoding::CompatibilityError: incompatible character encodings: ASCII-8BIT and UTF-8

The rest environment has not been changed, and the issue is related to the upgrade of the gem. Do you have an idea what could be wrong?

Ruby 2.6.5 (tested also on 2.7), Postgres 10 (tested also on 11), Sequel and Sequel_pg in the latest versions.

Having the same issue, downgraded back to pg 1.1 and everything is working fine 😕. I tested on Ruby 2.6.3 and Postgres 10 and 12, Sequel 5.27.0 (latest) and Sequel_pg 1.12.2 (latest).

This is actually an issue of sequel_pg. I filed a report here: jeremyevans/sequel_pg#34

Could you please try to remove sequel_pg from the Gemfile and retry with pg-1.2.0?

[meap]

Yes, you're right. It works without sequel_pg.

[bitencode]

Agreed, pg-1.2.0 works fine when sequel_pg is not used.

sequel_pg-1.12.4 and pg-1.2.1 fix this. Thank you @jeremyevans !
