Obscure error message "SQLDriverConnect = ?????????? (101) SQLSTATE=??1" for unicode psqlodbc #104

Description

@Jamedjo

Using psqlodbcw.so from brew install psqlodbc produces the following error in iODBC, while working fine in unixodbc:

/Library/Application\ Support/iODBC/bin/iodbctest "DSN=db_with_unicode_driver"

Driver Manager: 03.52.1623.0502
1: SQLDriverConnect = ??????????????????????????????????????????򠁹?????????????????????????????????? (101) SQLSTATE=??1
1: ODBC_Connect = ??????????????????????????????????????????򠁹?????????????????????????????????? (101) SQLSTATE=??1

Connection is successful with the ascii driver psqlodbca.so but returns incorrect characters.

Connection also works with either driver with unixodbc via isql -v db_with_unicode_driver.

I'm on an M1 mac and the driver is Mach-O 64-bit bundle arm64.

The obscure error message in a 3rd party app made this hard to diagnose, so if this is an error that needs to be fixed in the driver it would still be super useful to improve the error message here.
