This was originally reported at rubyinstaller-list by Jon.

With chcp 437, TestUnicodeEscape#test_basic fails with invalid byte sequence in UTF-8.

http://pastie.org/4688083


I got the following test failure with chcp 437 on Windows 7.


 1) Failure:
 test_basic(TestUnicodeEscape) [c:/Users/hiroshi/work/ruby/test/ruby/test_unicode_escape.rb:50]:
 Expected /^("?)\u00FC\1$/ to match "\"??\"\n".


echo command on Windows seems not to work properly against non-ascii characters with all code page.

I suggest a patch to use ruby instead of echo.
This patch works fine with chcp 437, 1252 and 65001. Jon also confirmed this.
