使用Qt Creator 16的Artistic Style格式化代码时，中文字符变成乱码//When using Qt Creator 16 to format code with Artistic Style, Chinese characters become garbled.

当我使用Qt Creator 16.0.0中Artistic Style插件格式化代码时，代码中的中文字符变成了乱码。

When I formatted the code using the Artistic Style plugin in Qt Creator 16.0.0, the Chinese characters in the code became garbled.

以下是一个简单的例子：

Here's a simple example:

//QtCBugExample.cpp
#include <stdio.h>
int main(int argc, char *argv[])
{
    printf("这是一段中文");
    return 0;
}

当我在Qt Creator 16.0.0中使用Artistic Style插件进行格式化之后，它变成了这样：

When I formatted it with the Artistic Style plugin in Qt Creator 16.0.0, it turns out like this:

//QtCBugExample.cpp
#include <stdio.h>
int main(int argc, char* argv[])
{	
    printf("杩欐槸涓€娈典腑鏂�");	
    return 0;
} 

为了验证故障，我使用cmd运行astyle.exe格式化相同的一个源文件，它工作正常，结果输出完全正确，而在Qt Creator中使用又会变成乱码，当我继续对此文件进行格式化时，乱码又会变成别的乱码，且越来越长。

In order to verify the fault, I use cmd to run astyle.exe to format the same source file, it works fine, the output is completely correct, but use in Qt Creator will become garbled, as I continue to format this file, garbled will become other garbled, and more and more long.

我意识到这是关于编码的问题，于是我查看并调试了Qt Creator 16.0.0的源码，想要找出问题所在。

I realized it was a encoding issue, so I looked at and debugged the Qt Creator 16.0.0 source code to figure out what the problem was.

我发现在formattexteditor.cpp (in src\plugins\texteditor) 的format方法中创建了一个Process，process启动了astyle.exe，格式化后的文本来自process的readAllStandardOutput方法（行 117），检查返回的文本可知从readAllStandardOutput方法返回的数据就是错误的。所以，错误发生在从输出的char*数据到QString的转换过程中。

I found that it created a Process object in the format method in formattexteditor.cpp (in src\plugins\texteditor), process launches astyle.exe, The formatted data comes from the readAllStandardOutput (line 117) method of process , and checking the returned data shows that the data returned from the readAllStandardOutput method is incorrect. So, the error occurs during the conversion from the output char* data to QString.

我尝试在Process创建（行 99）之后设置输出编码为UTF-8，如下：

I tried to set the output encoding to UTF-8 after Process creation (line 99), as follows:

//代码占位符
...
Process process;
process.setUtf8Codec();  // new added
QStringList options = input.command.options(); 
...

再次编译并尝试格式化代码，它完全工作正常，似乎问题解决了。

Compile again and try to format that source code, it works perfectly and seems to solve the problem.

另外，其它的代码格式化插件未做测试。

In addition, other code formatting plug-ins are not tested.

我希望在以后的版本中修复此错误。

I hope to fix this bug in a future release.
