Auto trim varchar vs trim char in 0.9.8

[McFris]

create procedure TEST_TRIM
returns (
    CH char(4),
    VARCH varchar(4))
as
begin
   CH = 'F   ';
   VARCH = 'F   ';
   suspend;
end

require github.com/nakagami/firebirdsql v0.9.8

conn.QueryRow(`select ch, trim(ch) trimch, varch, trim(varch) trimvarch from test_trim`).Scan(&a.Ch, &a.TrimCh, &a.VarCh, &a.TrimVarCh)

fmt.Printf("Char is: '%s', hex: %v\n", a.Ch, []byte(a.Ch))
fmt.Printf("Trim char is: '%s', hex: %v\n", a.TrimCh, []byte(a.TrimCh))

fmt.Printf("Varchar is: '%s', hex: %v\n", a.VarCh, []byte(a.VarCh))
fmt.Printf("Trim varchar is: '%s', hex: %v\n", a.TrimVarCh, []byte(a.TrimVarCh))

Result:
Char is: 'F', hex: [70]
Trim char is: 'F', hex: [70]
Varchar is: 'F ', hex: [70 32 32 32] <<<<<<<<<<<<<
Trim varchar is: 'F', hex: [70]

CHAR is trimmed
VARCHAR is not trimmed
These behaviors are as expected.

Is there possibility to make forced trimming similar for all text fields, at least as an option?
Similar to FIBPlus for Delphi?

I don't know if there is any agreement on whether char fields should be trimmed or not, but I can say that the postgresql drivers don't do it.

I don't know if there is any agreement on whether char fields should be trimmed or not, but I can say that the postgresql drivers don't do it.

And that's why we always have to write such a SQL query:
select trim(DATWEB) datweb, trim(CLIENT) client, trim(TIP) tip, trim(PROJECT) project from select_procedure
