这里从SUN jdk 1.4 源代码中找到一段使用jvm String 对象的getBytes的转换方式,相对简单和跨平台,不需要第三方库,但速度稍慢。函数原型如下: /* Convert between Java strings and i18n C strings */ JNIEXPORT jstring NewStringPlatform(JNIEnv *env, const char *str); JNIEXPORT const char * GetStringPlatfo...

查阅上篇博客的编码可知对于path部分Firefox、chrome、IE都是采用UTF-8编码格式,对于Query String部分Firefox、chrome采用UTF-8,IE采用GBK。至于为什么会加上%,这是因为URL的编码规范规定浏览器将ASCII字 符非 ASCII 字符按照某种编码格式编码成 16 进制数字然后将每个 16 进制表示的字节前加上“%”。
1 String s = "这是一段中文字符串"; 2 byte[] b = s.getBytes("UTF-8"); 3 String n = new String(b,"UTF-8"); 另外一个是已经被被废弃的 ByteToCharConverter 和 CharToByteConverter 类,它们分别提供了 convertAll 方法可以实现 byte[] 和 char[] 的互转。如下代码所示: ...
This method does not properly convert bytes into characters. As of JDK 1.1, the preferred way to do this is via the String constructors that take a java.nio.charset.Charset, charset name, or that use the platform's default charset. Java documentation for java.lang.String.String(byte[...
