Win7 Powershell回显>文本文件= Ruby2.2：无效的多字节字符（UTF-8）？

Question

Can I use echo from the powershell command line to create text files which Ruby can parse?

>>> echo "# foobar" > echo_test.rb
>>> ruby echo_test.rb
echo_test.rb:1: invalid multibyte char (UTF-8)

Notepad++ reports the encoding as UCS-2 Little Endian. I also tried echo'ing with the the header options mentioned in this thread: invalid multibyte char (UTF-8) Error, Ruby

eg

>>> echo "# encoding: utf-8" > echo_test.rb

and got the same error message.

You can change the encoding if you pipe it into Out-File

Example:

'# foobar' | Out-File -FilePath echo_test.rb -Encoding ascii
ruby echo_test.rb
