Because of the project encountered in the server-side jar package program, to the foreground message, the previous paragraph received a message garbled situation, so take the message string before sending the message to ASCII code before sending to the foreground, The foreground takes a solution that turns the ASCII code into a string before receiving a background message.1) Java method for turning strings into ASCII Public Staticstring Stringtoascii (String value) {StringBuffer SBU=NewString
For this (class) issue:(1) The problem occurs when the unicodeencodeerror–> description is Unicode encoding;(2) ' GBK ' codec can ' t encode character–> description is an issue that occurs when encoding Unicode characters as GBK;At this point, it is often most likely that the character of the Unicode type itself contains some characters that cannot be converted to GBK encoding.The solution is:
Scenario 1:
When encoding Unicode characters, add the ignore parameter, ignoring characte
When using PHP json_encode to handle Chinese, Chinese will be encoded, become unreadable, similar to the "\u***" format, if you want Chinese characters do not transcode, here are three ways1. Upgrade PHP, in PHP5.4, the problem is finally resolved, JSON added an option: Json_unescaped_unicode, so the name Incredibles, that is, JSON do not encode UNICODE.1 PHP 2 3 Echo json_encode ("Chinese", json_unescaped_unicode); 4 5 // "Chinese"2. UrlEncode the Chinese characters first and then use the Json_

If you convert the string to GBK encoding:s = "unicode字符串"s_gbk = s.encode("gbk")
If you convert the string to UTF-8 encoding:s_utf8 = s.encode("utf-8")
If you convert a string of GBK format to the UTF-8 format, you need to convert the GBK format to Unicode format and then convert the Unicode to the encoding in UTF-8 format:gbk_to_utf8 = s_gbk.decode("gbk").encode("utf-8")
It is important to note that encode the subse

The principle is very simple, because the GB2312/GBK is Chinese two bytes, these two bytes is a range of values, and utf-8 Chinese characters are three bytes, also have a range of values for each byte. The English language is less than 128, regardless of the encoding, and occupies only one byte (except all corners).
If it is a file-form code check, you can also check Utf-8 's BOM information directly. To say, directly on the function, this function is used to check the string and

2, then we open the pop-up menu option to find the "transcoding" button;
3, in the pop-up table chart click Add File button;
4, then we find to prepare the conversion of the video file, the effect shown in the following figure;
