StringencodedString=newString(bytes,"UTF-8"); 1. 在这里,我们通过使用String类的构造函数,将字节数组和UTF-8编码作为参数来创建一个新的String对象。 步骤4:将字节序列转换为UTF-8编码的String对象 最后,我们将把字节序列转换回UTF-8编码的String对象。以下是示例代码: Stringutf8String=newString(encodedString....
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(); StringBuffer outBuffer=newStringBuffer(...

有时我们需要将NSString转换为UTF-8,前几天发现苹果弃用了以前的旧接口,下面是查找了一些资料后,整理的代码 /** * 编码 */NSString*url=@"http://www.jianshu.com/u/7be4a0163a7f?p1=%+&sd &p2=中文";// 旧方法NSString*encodedValue=[url stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncodin...
icu::UnicodeString的toUTF8String方法可以将一个其他编码的字符串自动转为utf8。
(nullable NSString *)stringByReplacingPercentEscapesUsingEncoding:(NSStringEncoding)enc // 1.创建 NSURL 对象// (1)获取 urlStringNSString*urlString=[NSString stringWithFormat:@"http://www.baidu.com"];(2)编码转换// NSString *newStr = [urlString stringByReplacingEscapesUsingEncoding:NSUTF8String...
检测字符串编码可以用扒拉自Mozilla的uchardet库，转换可以用ICU，嫌大用iconv凑合一下。
