Okay, so forget Delphi 2009 compatibility for the moment (I don't use
Delphi). So does this mean to use "official" FPC Unicode, I can't use
{$mode objfpc} any more?

No problem, I changed the example to a console program and used
WriteLn() instead.
Does WriteLn() work correctly with Unicode text? Will it detect my
console encoding used in mate-terminal or xterm under FreeBSD? If not,
what else must I do to test this Unicode support?

As past experience has shown me, the wiki is a very unreliable source -
often things are way out of date, or "concepts" was documented but never
removed when something else was decided etc.
But I'll spend my lunch time reading the wiki page in question and see
if anything helps. But like I said, the experience thus far is anything
but ideal or straight forward.

Both. I can't follow the examples shown in the Delphi_and_Unicode.pdf,
because they simply don't compiler or don't run.
The wiki pages doesn't have a single compilable "test program" example
that can get you going.
Here is the Lazarus Forum discussion on FPC's new String support in 3.0.
I tried that example on my FreeBSD system too, and the console output
was total rubbish no matter what I tried.
