STDIN和Powershell - 如何使编码匹配？

Question

我有Ruby(1.9.3)和Powershell的问题.

我需要编写一个交互式控制台应用程序,它将处理波兰语的句子.我得到了帮助,可以使用波兰语变音符号检索ARGV元素,但标准输入不能按照我的要求运行.

代码图:

# encoding: UTF-8
target = ARGV[0].dup.force_encoding('CP1250').encode('UTF-8')
puts "string constant = dup?"
puts "dup?".bytes.to_a.to_s
puts "dup?".encoding

puts "target = " +target
puts target.bytes.to_a.to_s
puts target.encoding
puts target.eql? "dup?"

STDIN.set_encoding("CP1250", "UTF-8") 
# the line above changes nothing, it can be removed and the result is still the same
# I obviously wanted to mimic the ARGV solution

target2 = STDIN.gets
puts "target2 = " +target2
puts target2.bytes.to_a.to_s
puts target2.encoding
puts target2.eql? "dup?"

输出:

string constant = dup?
[100, 117, 112, 196, 133]
UTF-8
target = dup?
[100, 117, 112, 196, 133]
UTF-8
true
dup? //this is fed to STDIN.gets
target2 = dup
[100, 117, 112]
UTF-8
false

显然Ruby永远不会从STDIN.gets获得第四个字符.如果我写一个更长的字符串,dup?lalala仍然只有三个初始字节出现在程序中.

• 我已经尝试枚举字节并使用getc循环,但它们似乎永远不会到达Ruby(它们丢失在哪里？)
• 我用过chcp 65001(似乎没有改变一件事)

• 我已将$ OutputEncoding更改为[Console] :: OutputEncoding; 它现在看起来像这样:

   IsSingleByte      : True
   BodyName          : ibm852
   EncodingName      : ?rodkowoeuropejski (DOS)
   HeaderName        : ibm852 
   WebName           : ibm852
   WindowsCodePage   : 1250
   IsBrowserDisplay  : True
   IsBrowserSave     : True
   IsMailNewsDisplay : False
   IsMailNewsSave    : False
   EncoderFallback   : System.Text.InternalEncoderBestFitFallback
   DecoderFallback   : System.Text.InternalDecoderBestFitFallback
   IsReadOnly        : True
   CodePage          : 852

如何在Powershell中正确阅读波兰语变音符号？

我查到了一些相关的信息。不确定这是否是正确的信息。但是，嘿，OP 已经有了另一个解决方案。
