Subject: [ruby-core:33471] Re: [Ruby 1.9-Bug#4097][Open] Unexpected result of STDIN.read on Windows

Hello,

WindowsXP seems have a bug at read functions under multibyte console inputs.
I found a issue of coming from same bug of Windows. :-(

does anybody have a good workaround idea ?

> ruby -ve 'a=STDIN.read(6);p [a,a.length];a=STDIN.read(2);p [a,a.length];'
ruby 1.9.3dev (2010-11-30 trunk 29978) [i386-mswin32_100]
���������������aiueo
["\x82\xA0\x82\xA2\x82\xA4", 6]
["iu", 2]
