qDebug() 的错误输出(UTF - 8) [英] Wrong output of qDebug() (UTF - 8)

问题描述

我正在尝试存储一个带有特殊字符的字符串::

I'm trying to store a string with special chars::

qDebug() << "ÑABCgÓ";

输出:(在这里我什至无法输入正确的输出，在 Ã & Ã 之后缺少一些垃圾)ÃABCgÃ

Outputs: (here i can't even type the correct output some garbage is missing after à & Ã) ÃABCgÃ

我怀疑某些 UTF-8/Latin1/ASCII，但找不到输出到控制台/文件的设置.我在代码中写的内容:ÑABCgÓ".

I suspect some UTF-8 / Latin1 / ASCII, but can't find the setting to output to console / file. What i have written in my code : "ÑABCgÓ".

(Qt:4.8.5/Ubunto 12.04/C++98)

推荐答案

您可以使用 QString QString::fromUtf8(const char * str, int size = -1) [static] 作为示例代码如下所示.这是QString存在的主要原因之一.

You could use the QString QString::fromUtf8(const char * str, int size = -1) [static] as the sample code presents that below. This is one of the main reasons why QString exists.

查看文档了解详情:

http://qt-project.org/doc/qt-5.1/qtcore/qstring.html#fromUtf8

#include <QString>
#include <QDebug>

int main()
{
    qDebug() << QString::fromUtf8("ÑABCgÓ");
    return 0;
}

建筑(根据您的场景定制)

g++ -fPIC -I/usr/include/qt -I/usr/include/qt/QtCore -lQt5Core main1000.cpp && ./a.out

输出

"ÑABCgÓ"

话虽如此，根据您的语言环境，只需 qDebug() <<"ÑABCgÓ"; 可以像这里一样工作，但建议通过明确询问 UTF-8 处理来确保.

That being said, depending on your locale, simply qDebug() << "ÑABCgÓ"; could work as well like in here, but it is recommended to make sure by explicitly asking the UTF-8 handling.
