我们可以使用getBytes("UTF-8")方法将String对象转换为UTF-8编码的字节数组。 下面是一个简单的示例代码: publicclassStringToUtf8Example{publicstaticvoidmain(String[]args){Stringstr="Hello, 世界!";try{byte[]bytes=str.getBytes("UTF-8");System.out.println(Arrays.toString(bytes));}catch(UnsupportedEnco...
std::string utf8String=convertToUtf8(gbkString); if(!utf8String.empty()){ std::cout<<"UTF-8 String: "<<utf8String<<std::endl; } return0; } 请确保在使用之前安装了ICU库,并将编译命令中添加对应的链接参数。该示例代码可以将GBK编码的字符串转换为UTF-8编码的字符串,并输出结果。
DWORD nBytes=0;//UFT8可用1-6个字节编码,ASCII用一个字节 UCHAR chr; BOOL bAllAscii=TRUE; //假设所有都是ASCII, 说明不是UTF-8 for(int i=0; i<length; ++i) { chr= *(str+i); if( (chr&0x80) != 0 ) // 推断是否ASCII编码,假设不是,说明有可能是UTF-8,ASCII用7位编码,但用一个字节...
1、单纯的Unicode 转码 String a = "\u53ef\u4ee5\u6ce8\u518c"; a=newString(a.getBytes("UTF-16"),"Unicode"); 2、String 字符串中含有 Unicode 编码时,转为UTF-8 publicstaticString decodeUnicode(String theString) {charaChar;intlen =theString.length(); ...
java不同编码之间进行转换,都需要使用unicode作为中转。String str = "任意字符串";str = new String(str.getBytes("gbk"),"utf-8");备注说明:str.getBytes("UTF-8"); 意思是以UTF-8的编码取得字节 new String(XXX,"UTF-8"); 意思是以UTF-8的编码生成字符串 举例:public static String ...
