lc_numeric and negative-prefix

Hi.

 

We're having this thread over at https://github.com/impossibl/pgjdbc-ng/issues/420

 

Can anybody shed som light on when negative-prefix is supposed to be respected by PG's formatting-functions?

In lc_numeric='nb_NO.UTF-8' negative-prefix is '−'(8722), not '-'(45), at least in the JAVA-world, but it seems the JDBC-driver must use lc_numeric='C' when parsing server output.
