Delphi PostgreSQL Unicode
If Delphi Project raise exception class EDatabaseError with message ... Type mismatch for field NAME, expecting: String actual: WideString.
Using the Devart dbExpress driver (4.40.0.14) the following params must be set on TSQLConnection:
UseUnicode=True
Charset=utf8
this way stringfields get mapped into TWideString field, so the original issue has been solved.
