Thank you. I added above test and some other tests.
I added one more mode setting for safe.

"make test" passed.
"make test-all" failures and errors were same as before patch.

Bug #5714: Unexpected error of STDIN#read with non-ascii input on Windows XP
http://redmine.ruby-lang.org/issues/5714

Author: Heesob Park
Status: Open
Priority: Normal
Assignee: Usaku NAKAMURA
Category: build
Target version: 
ruby -v: -


When the input contains non-ascii character, STDIN#read raised Permission denied or Invalid argument error with MSVC compiled version on Windows XP.

	C:\work>ruby -ve 'p STDIN.read(5)'
	ruby 2.0.0dev (2011-12-05 trunk 33955) [i386-mswin32_100]
	???κΈ?abcd
	-e:1:in `read': Permission denied - <STDIN> (Errno::EACCES)
		from -e:1:in `<main>'

	C:\>irb
	irb(main):001:0> STDIN.read(5)
	???κΈ?abcd
	Errno::EINVAL: Invalid argument - <STDIN>
		from (irb):1:in `read'
		from (irb):1
		from c:/usr/bin/irb.bat:19:in `<main>'

If the input is ascii only, STDIN.read works fine.

	C:\work>ruby -ve 'p STDIN.read(5)'
	ruby 2.0.0dev (2011-12-05 trunk 33955) [i386-mswin32_100]
	abcdefg
	"abcde"

	C:\>irb
	irb(main):001:0> STDIN.read(5)
	abcdefg
	=> "abcde"

It is odd but the Mingw compiled version works fine.

	C:\work>ruby -ve 'p STDIN.read(5)'
	ruby 2.0.0dev (2011-12-05 trunk 33955) [i386-mingw32]
	???κΈ?abcde
	"\xC7\xD1\xB1\xDBabc"

And Ruby 1.9.3p0 works fine.
	
	C:\>ruby -ve 'p STDIN.read(5)'
	ruby 1.9.3p0 (2011-10-30 revision 33570) [i386-mswin32_100]
	???κΈ?abcd
	"\xC7\xD1\xB1\xDBabc"
