调用fopen或open时使用什么编码? [英] What encoding used when invoke fopen or open?

问题描述

当我们在Linux中调用"open"之类的系统调用或在"fopen"之类的stdio函数中调用时，我们必须提供一个"const char * filename".我的问题是这里使用的编码是什么?是utf-8还是ascii或iso8859-x?是否取决于系统或环境设置?

When we invoke system call in linux like 'open' or stdio function like 'fopen' we must provide a 'const char * filename'. My question is what is the encoding used here? It's utf-8 or ascii or iso8859-x? Does it depend on the system or environment setting?

我知道在MS Windows中有一个_wopen接受utf-16.
