在Unicode和默认语言环境之间转换 [英] Converting between Unicode and default locale
问题描述
你好，
是否有便携式（至少用于VC.Net和g ++）方法转换文件
wchar_t和char，使用标准库？我可能已经错过了很多东西
很明显，但是在Josuttis''标准C ++
图书馆中的codecvt部分没有帮助，我是还在等待Langer的交付
标准C ++ IOStreams和Locales。
谢谢，
Keith MacDonald

Hello,
Is there a portable (at least for VC.Net and g++) method to convert text
between
wchar_t and char, using the standard library? I may have missed something
obvious, but the section on codecvt, in Josuttis'' "The Standard C++
Library", did not help, and I''m still awaiting delivery of Langer''s
"Standard C++ IOStreams and Locales".
Thanks,
Keith MacDonald

我在L& K的副本中读到没有内置支持
宽字符流
。类型''wchar_t''仅用于
来实现多字节流i / o。
另请注意，根据平台的字节大小，
并非所有Unicode值都必须符合类型
''char''。

I read in my copy of L&K that there is no built-in support
for wide character streams. Type ''wchar_t'' is only used
to implement multibyte stream i/o.
Also note that depending upon your platform''s byte size,
not all Unicode values will necessarily fit into type
''char''.

Mulstibyte使用多个字符来编码字符。
wchar_t是固定大小的宽字符。但我知道你的意思是什么。
是的，这是国际化支持的一个主要缺陷。
我有在comp.std.C ++游说修复此问题（将wchar_t
接口添加到极少缺乏它的几个地方
就像fstreams中的文件名等...） 。不幸的是，
我从
标准社区的其余部分得到了很多婊子和呻吟，他们没有认真对待
更有问题的字符编码如日语。
Mulstibyte is using more than one char to encode a character.
wchar_t is fixed size wide characters. But I knew what you
meant.
Yes, it''s a major defect in the internationalization support.
I have lobbied in comp.std.C++ to fix this (adding wchar_t
interfaces to the few places that are sorely lacking it
like the filenames in fstreams, etc...). Unfortunately,
I get a lot of bitching and moaning from rest of the
standard community who haven''t seriously dealt with
some of the more problematic character encodings such as Japanese.
