FireDAC TFDConnection: problem with exclamation mark at the end of the password

Hi,

we are using FireDAC TFDConnection to connect to a PostgreSQL database (version 9.6.3 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-11), 64-bit).

Our code looks like:

    FDConnection.LoginPrompt := False;
    FDConnection.Params.UserName := xxx;
    FDConnection.Params.Password  := password;

    FDConnection.Connected := true;

Everthing is working fine, except the password contains an exclamation mark at the end, other positions for an exclamation mark inside the password are no problem. The raised exception is a native EFDDBEngineException.

Any idea to avoid this exception?

Thank you,

best regards, Christoph
