比较C ++中的中文字符串 [英] Comparing Chinese Strings in C++

问题描述

我正在跨平台开发，通过该平台我可以将基于UTF-8的消息数据(包含汉字)从Windows发送到Linux.

现在在Linux端(使用C ++)，我需要比较每行以找到我正在寻找的中文字符串，并根据是否找到中文字符串进行处理.

问题是，即使我可以看到Im在Linux端读取的消息中也存在中文字符串，但比较找不到它.我正在使用std :: wstring并使用wstring的find()方法.

当我在Linux中将消息打印到标准输出(控制台)时，我可以看到中文字符串，但是find找不到它.在Linux方面，我为中文字符串添加了"L"前缀，即L< chinese string =">.

非常感谢您提供任何帮助，帮助您弄清为什么即使存在中文字符串也找不到它.

Hi,

Im working on a cross plateform development whereby Im sending a UTF-8 based message data (containing Chinese characters) from Windows to Linux.

Now on the Linux side (using C++), I need to compare each line to find the Chinese string Im looking for and do the processing based on if I find the Chinese strings.

The question is that even though I can see the Chinese string exist in the message that Im reading on the Linux side, the comparison is not finding it. Im using std::wstring and using the find() method of the wstring.

When I print the message to the standard output (console) in Linux, I can see the Chinese string, but find is not finding it. In the Linux side, I am prefixing the Chinese string with "L" i.e. L "<chinese string="">".

Will appreciate any help in figuring out why the Chinese string is not being found even though it exists.

THanks
