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 Stringtoasc

Today encountered a thorny problem, in the old project Riga some JS files and old project coding format inconsistencies appear garbled. The old page is GB2312, the link into the JS file is UTF-8, two files can not be transferred format. The first idea is to convert the Chinese in the JS file to Unicode encoding. This approach is based on the expense of readability of the conditions, the Chinese all become a password. Afterwards think that there should be a better way, and then go to Baidu, t
