[ruby-core:52188] [ruby-trunk - Bug #7758] Ruby on Windows crashes when active codepage is codepage 65001 and outputting unicode character

Issue #7758 has been updated by usa (Usaku NAKAMURA).

Assignee changed from usa (Usaku NAKAMURA) to mame (Yusuke Endoh)

Sorry for late reply, luis.
Please commit it to trunk.

mame-san, this is reproducible SEGV bug.
So I think we need to backport it into ruby_2_0_0 (and ruby_1_9_3).

Bug #7758: Ruby on Windows crashes when active codepage is codepage 65001 and outputting unicode character

=begin
I have a script that contains the unicode BOX_DRAWINGS_LIGHT_VERTICAL_AND_RIGHT character (http://www.fileformat.info/info/unicode/char/251c/index.htm). When the console code page is set to 65001 (utf-8), both ruby 1.9.3 p125 and p374 crash, but ruby 1.8.7 p357 does not crash (nor does it output the character correctly). When the code page is set to 437, ruby 1.9.3 (both versions) correctly output the character, while ruby 1.8.7 outputs the wrong character again.

I don't care about ruby 1.8.7 so much, but I would expect ruby 1.9.3 to output the correct character, especially since the console codepage is set to 65001 (utf-8).

Here is my script:

 # -*- coding: utf-8 -*-
 puts "a"
 puts "├"

I verified that the file is correctly encoded:

 C:\test>od.exe -t x1 test65001.rb
 0000000 23 20 2d 2a 2d 20 63 6f 64 69 6e 67 3a 20 75 74
 0000020 66 2d 38 20 2d 2a 2d 0a 70 75 74 73 20 22 61 22
 0000040 0a 70 75 74 73 20 22 e2 94 9c 22 0a 0a

Note the UTF-8 sequence `e2 94 9c`

Here are the codepage settings in the registry:
 C:\test>reg query hklm\SYSTEM\CurrentControlSet\Control\Nls\CodePage /v acp
 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Nls\CodePage
    acp    REG_SZ    1252
 C:\test>reg query hklm\SYSTEM\CurrentControlSet\Control\Nls\CodePage /v oemcp

    oemcp    REG_SZ    437

Based on the line `c:/Ruby193p374/lib/ruby/1.9.1/i386-mingw32/enc/iso_8859_1.so` it makes me think ruby is looking at the registry for the active code page (cp1252) instead of calling GetConsoleOutputCP to see which codepage it should be using, but that is just a guess.
