That's filesystem encoding.
ospath is to interface with the system.

Maybe my solution is wrong.
But Dir.getwd should encoded into internel encoding,am I right?

[nobu (Nobuyoshi Nakada)]

It's not.
Path name is not the target of automagical conversion.

[[e-mail] (贾 延平)]

You mean the code
File.getwd+'some utf-8 file name'
Should raise encoding compitable error?

Where I can see the ruby's internal design principle for encoding?When encode to internal encoding?When do not?
The doc:http://www.ruby-doc.org/core-2.0/Encoding.html say some thing but do not tell why.

[nobu (Nobuyoshi Nakada)]

If the filesystem encoding is not UTF-8.
From when did you think it is always UTF-8?

Maybe I did not speake clearly，When we write ruby code,we should consider the string create is internal encoding by default,and if internal encoding != filesystem encoding when we use the File.getwd result with other strings that will be problem.
