There are five main areas:
One.. HTML page UTF-8 encoding problem
Two. PHP page UTF-8 encoding problem
Three. The problem of using UTF-8 encoding in MySQL database
Four. JS-related UTF-8 coding problem
Five. Flash-related UTF-8 coding problem

into several subsequence, each subsequence is ordered. Then the ordered Subsequence is merged into the whole ordered sequence.

(1) The basic idea: all the values to be compared (positive integer) unified to the same number of digits, the number of short digits before the number 0. Then, start at the lowest bit, and then sort it one at a time. This is done from the lowest b
Experiment 8: PS/2 module ②-keyboard and key combination
In experiment 7, we learned how to read the code and the code break sent from the PS/2 keyboard. However, the experiment content is just a one-click press and then release, just a simple button. However, in experiment 8, we learned the key combination behavior.

UTF code
The UTF-8 is to encode the UCS in 8-bit units. The encoding method from UCS-2 to UTF-8 is as follows:
UCS-2 encoding (16-in-system)
UTF-8 byte stream (binary)
0000-007f
0xxxxxxx
0080-07ff
110xxxxx 10xxxxxx

In PHP development sometimes use transcoding functions, such as iconv (), mb_convert_encoding () function, when using the function transcoding or decoding time we sometimes need to determine the current string encoding type, rather than whether it is utf-

The first mistake that beginners can easily make on this topic is to write the following expression to evaluate it.

Over the next 50 years, people have been trying to find a possible 16-square-sum equation, but all failed, so they began to wonder if s

The UTF-8 is to encode the UCS as a 8-bit unit. The encoding from UCS-2 to UTF-8 is as follows:
