Questions about Java.net.URLEncoder.encode () and Java.net.URLEncoder.encode () in the JDK in Android.jar

Problem: Recently done in the project, because to use the socket, so it is inevitable that the code to "GBK", but found in the use of Android.jar in the Java.net.URLEncoder.encode ("Kanji", "GBK") When coding, it is found to lose half of the last character, such as "Min" code became "%C3" instead of the correct "%c3%d6", and then in another Java project demo, found Java.net.URLEncoder.encode ("Kanji", "GBK") Without this problem, it began to be depressed ...  try: Try 1: Find the JDK in the Java.net.URLEncoder class implementation and Android.jar is completely different, guess whether the underlying implementation is not the same cause the above problem, Then I try to copy the Java.net.URLEncoder class from the JDK into my project and find that the problem is still, and this idea fails!  try 2: by discovering that it may be related to different platforms, my project uses the Android network box, 4.4.2, Third-party manufacturer OEM system, that other Android platform can run correctly?          start trying, Using another small Android project for Java.net.URLEncoder.encode to do a small demo apk, run on another Android phone, found to be able to run correctly, can get the correct results. Good platform-agnostic? The original is really related to the platform!!   Problem reason: by discovering the GetBytes () that seems to be a string, the System.arrayscopy () is used in the native method to intercept the byte of a char (specifically, not too deep, and so on, the project is urgent).   Solution: Fortunately, the transmission of data in this project only urlencode the Chinese characters, so, some tools will need to transfer the data in the Chinese characters through the regular pick out, and then the Chinese characters in the use of the string after the Chinese character only a string, such as: "1", and then removed as long as the Chinese part of the code (this code is also a tool method, just converts a byte array into a 16-character string, and then the encoding of each Chinese characters separated by a space, and then take the process of using string.spit () the encoding of each Chinese character string[]), Then the original string of the Chinese character and the encoding after the character string to replace, this Shang method to complete the .  code:
