1. As a result of the project encountered in the server-side jar package program, send a message to the front desk, the previous paragraph received the message garbled situation, so take the message before sending the message string into an ASCII code before sending to the front desk, The foreground takes a solution that turns the ASCII code into a string before receiving the background message. 1 Java meth

The reason is that in the simplified Chinese environment of the Win7 system, the Chinese encoding format used by default is the GBK format, and Eclipse's default encoding format is the encoding format of the system in which it is used. Therefore, you need to modify eclipse in the default encoding format.Steps Open Eclipse,windows-Preferences ...Navigate to General, Workspace on the left, click Other in the text file encoding on the right, select UTF-8, and click OK.Step 2 Windows-Preferences ...

. Because the computer can only store 0-1 form of machine code, in fact, 0-1 corresponds to the computer hardware in a switch to open and close. For programmers, it's obviously unfriendly to write a program with 0-1 of these machine codes, so there is the programming language, the programming language is some we can read the character, it greatly liberated the programmer, but on the other hand to human friendly also means that the machine is not friendly, the computer is not recognize these char

This article illustrates the way JavaScript implements Unicode and ASCII conversion to each other. Share to everyone for your reference, specific as follows: I hope this article will help you with JavaScript programming.

Copy Code code as follows: Class ASCII { function decode ($STR) { Preg_match_all ("/(d{2,5})/", $str, $a); $a = $a [0]; foreach ($a as $dec) { if ($dec { $utf. = Chr ($DEC); } else if ($dec { $utf. = Chr (($dec-($dec% 64))/64); $utf. = chr (128 + ($dec% 64)); } Else { $utf. = Chr (224 + ($dec-($dec% 4096))/4096); $utf. = chr (128 + (($dec% 4096)-($dec% 64))/64); $utf. = chr (128 + ($dec% 64)); } } return $UTF; } function e
