Hi Noel,
Thanks Tomas. I didn't see your promise to look at the problem.
Sorry, it took somewhat longer, but the results are here:
1) It works as expected if _not_ using unit Crt.
2) There is a bug in implementation of unit Crt for Windows. This bug
stems from May 2006 already and it was a result of a patch from Maxim
Ganetsky trying to fix bug #6785
(http://bugs.freepascal.org/view.php?id=6785). Since that patch, all
output with unit Crt uses the so called ANSI code page under Windows
which is IMHO wrong. I've added a comment to bug #6785 and filed a
new bug report (http://bugs.freepascal.org/view.php?id=16846) - you
may want to monitor that one in order to be notified when it gets
fixed.
Until the bug is fixed, there are several possible solutions for you,
e.g.:
- You may comment line 699 (and preferably also line 743) in your
local copy of rtl/win/crt.pp (trunk version from SVN) and recompile
RTL (and packages). That isn't a complete fix, but it should probably
be sufficient for your needs.
- If you only need to output this one particular character, you may
do so using the particular Win32 API directly. Admittedly not very
nice and certainly not portable, but at least a possible workaround.
- If you don't need unit Crt, you may simply remove it from your uses
clause.
I have just relied on email replies for comments etc. How do I look at
all
comments, other questions, etc on the Web?
Sorry, I'm not sure if I understand this question. Do you refer to an
archive of this mailing list? If so, you can find a link on the FPC
WWW pages (under Mailing lists).
Hope this helps
Tomas

I still intend to have a look at it (as promised previously), just had no
time for that (if noone else provides answer till then).
