Hi,
We find gdb.base/printcmds.exp fails a lot on windows host, like this,

 p ctable1[163]
 $204 = 163 '£'
 (gdb) FAIL: gdb.base/printcmds.exp: p ctable1[163]

however, on linux host,

 p ctable1[163]
 $205 = 163 '\243'
 (gdb) PASS: gdb.base/printcmds.exp: p ctable1[163]

The printing related code is in valprint.c:print_wchar,

  if (gdb_iswprint (w) && (!need_escape || (!gdb_iswdigit (w)
					    && w != LCST ('8')
					    && w != LCST ('9'))))
    {
      gdb_wchar_t wchar = w;

      if (w == gdb_btowc (quoter) || w == LCST ('\\'))
	obstack_grow_wstr (output, LCST ("\\"));
      obstack_grow (output, &wchar, sizeof (gdb_wchar_t));
    }
  else
   {
      // print W in hex or octal digits
   }

When I debug gdb on different hosts, I find
on windows host, gdb_iswprint (iswprint) returns true if 'w' is 163.
However, on linux host, iswprint returns false if 'w' is 163.  Looks
this difference is caused by the charset.  On Linux host,
the target-charset is ANSI_X3.4-1968, while on windows host, the
target-charset is CP1252.

We can see how target-charset affects the output.  On linux host,

 (gdb) set target-charset ASCII
 (gdb) p ctable1[163]
 $1 = 163 '\243'
 (gdb) set target-charset CP1252
 (gdb) p ctable1[163]
 $2 = 163 '£'

we can print the pound sign too, and it shows target-charset does
affect the output.

This patch is to set target-charset temporarily to ASCII for some
charset-sensitive tests.  Tested on arm-none-eabi and
powerpc-linux-gnu on mingw32 host.  More than one hundred fails are
fixed.

Sorry about the wait, Yao.

I'm a little unsure about this one, because I am not sure that all
targets will support the "ASCII" charset. For instance, I logged on
a Tru64 machine, and "local -a" only returned:

    POSIX
    en_US.ISO8859-1

On the other hand, a GDB built with libiconv supports ASCII (and much
more). So I'm inclined to try your patch. Give it another couple of
days, and if noone objects, then go ahead and commit.

Patch is pushed in.  Please shout if it causes troubles on some targets.

Hi.

No objections per se, but I'm inclined to think we should make ASCII
the default for every test (or some similar charset) (i.e., set it
where we set width to zero), and require tests that wish a different
charset to explicitly request it.
