Linux 下QT 5中中文乱码问题

oathupdate 2015-02-11 11:39:47

看网上的方法是
直接将 QTextCodec::setCodecForLocale(QTextCodec::codecForName(“UTF8”)) 至于QApplication实例之前即可解决;
但是我放了之后没有解决。汉字还是会乱码。
我的汉字是char*类型的并且汉字是从windows下用Socket发过来的。
我的是Ubuntu 文字是支持简体中文的。

void QTextCodec::setCodecForCStrings ( QTextCodec * codec ) [static] Sets the codec used by QString to convert to and from const char * and QByteArrays. If the codec is 0 (the default), QString assumes Latin-1. Warning: Some codecs do not preserve the characters in the ASCII range (0x00 to 0x7F). For example, the Japanese Shift-JIS encoding maps the backslash character (0x5A) to the Yen character. To avoid undesirable side-effects, we recommend avoiding such codecs with setCodecsForCString(). Warning: This function is not reentrant. See also codecForCStrings() and setCodecForTr(). void QTextCodec::setCodecForLocale ( QTextCodec * c ) [static] Set the codec to c; this will be returned by codecForLocale(). If c is a null pointer, the codec is reset to the default. This might be needed for some applications that want to use their own mechanism for setting the locale. See also codecForLocale(). void QTextCodec::setCodecForTr ( QTextCodec * c ) [static] Sets the codec used by QObject::tr() on its argument to c. If c is 0 (the default), tr() assumes Latin-1. If the literal quoted text in the program is not in the Latin-1 encoding, this function can be used to set the appropriate encoding. For example, software developed by Korean programmers might use eucKR for all the text in the program, in which case the main() function might look like this: int main(int argc, char *argv[]) { QApplication app(argc, argv); QTextCodec::setCodecForTr(QTextCodec::codecForName("eucKR")); ... } Note that this is not the way to select the encoding that the user has chosen. For example, to convert an application containing literal English strings to Korean, all that is needed is for the English strings to be passed through tr() and for translation files to be loaded. For details of internationalization, see Internationalization with Qt. Warning: This function is not reentrant. See also codecForTr() and setCodecForCStrings().

把收到的数据以 16 进制打印出来看看是什么编码

无论是 GB2312 还是 UTF8 都可以正常显示的，不一定非要转换成 UTF8

吧十六进制的打印出来了可以就是几个数字怎么看是什么编码呢

我弄好了谢谢是根据这个代码弄好的。可能是我没表达清楚谢谢了 int GB2312ToUTF8(char* srcStr, char* desBuff, size_t desBuffLength) { assert(strlen(srcStr)>0); size_t iLen = strlen(srcStr); iconv_t cd; cd = iconv_open("utf-8","gb2312"); assert(cd != 0); iconv(cd, &srcStr, &iLen, &desBuff, &desBuffLength); iconv_close(cd); return desBuffLength; }
