XMLString :: transcode无法在Linux中转换UNICODE char [英] XMLString::transcode not able to convert UNICODE char in Linux

问题描述

有一个字符串Ë = D5 +！？！，当它存储在char *变量中时，它会被转换为Ã = D5 +!? ！。我猜这是由于字节大小。



Ë的ASCII值是203（UNICODE字符）



const XMLCh * pXValue =Ë = D5 +！？！;

char * pValue = XMLString :: transcode（pXValue）;





调用函数 XMLString :: transcode（Xerces Library函数）后，pValue包含Ã= D5 + ！？！错误的字符串。



注意：在Windows中它工作正常但在Linux中会产生问题。



语言：VC ++

平台：Windows和Linux

框架：Visual Studio 2012

There is a string "Ë=D5+"!?!", when it is stored in char* variable it is converted to "Ã=D5+"!?!". I guess this is due to byte size.

ASCII value of Ë is 203 (UNICODE character)

const XMLCh* pXValue = "Ë=D5+"!?!";
char* pValue = XMLString::transcode( pXValue );


After calling of function XMLString::transcode(Xerces Library function), pValue contain "Ã=D5+"!?!" string which is wrong.

Note : In Windows it is working fine but in Linux it creates problem.

Language : VC++
Platform : Windows and Linux
Framework : Visual Studio 2012

推荐答案

这看起来像源文件编码问题。你的.cpp文件是用UTF-8编码的吗？您可以在GCC命令行上使用

This looks like a source file encoding issue. Is your .cpp file encoded in UTF-8? You can use the

-finput-charset=UTF-8

来指定源文件的编码。

感谢Vaclav Zeman的回复，我按照你的建议尝试但是没有解决我的问题。



XMLCh在Window上代表2字节，在Linux上代表这个值（Ë= D5 +！？！）需要4个字节的表示。

所以我创建了一个将4个字节转换为2个字节的函数，它起作用了。

Thanks Vaclav Zeman for reply and I tried as you suggested but that didn't resolve my problem.

The XMLCh represent 2 byte on Window and as well on Linux but this value( "Ë=D5+"!?!" ) require 4 byte representation.
So I create a function which convert 4 byte to 2 byte and it worked.
