PHP character encoding conversion class,
support for ANSI, Unicode, Unicode big endian, UTF-8, Utf-8+bom to convert each other.
Four common text file encoding methods
ANSI Code:
No file header (file encoding at the beginning of the symbolic byte)
ANSI encoded alphanumeric account of one byte, Chinese characters accounted for two bytes
Carriage return line break, single byte, hexadecimal representation 0d

Title Link: http://acm.zju.edu.cn/onlinejudge/showProblem.do?problemId=4682As everybody knows, the sum of the interior angles of a triangle on a plane are always the degree. But that's not true when the triangle are on spherical surface. Given a triangle on a spherical surface, which is asked to calculate the sum of the interior angles of the triangle.Formally, g
Source: Unicode to Gbk,gnk to Unicode, to solve the problem of FATFS the ROM occupied by the Chinese Code tableBefore the use of the 512KB ROM STM32, but recently used only 128KB, want to use FATFS display support long filenames, found that add cc936.c after the ROM is not enough, decided to store this bidirectional code table in the external memory, flash or SD card line, Only can read on the line;The enco
That is: How does a obtuse triangle divide to make it consist of a finite number of acute triangle and make these acute triangle the fewest? Answer: Divided into 7 acute triangle;. methods: A convex Pentagon was made by using an obtuse angle for one side of the middle part of the edge;Take Pentagon inside a point, resp
Test instructions: To a series of triangles, the nth layer of the number of elements is n, from the top down, each element can choose with their own recent two lower elements down, similar to a binary tree, the shortest way. [2], [3, 4], [6,5, 7], [4,1, 8,3]Note: Here can 2->3>5>1, also can 2->4>5->1, the compartment adjacent can walk.Idea: You can go up from the bottom, or you can go down from the top. Is the space of O (n), the complexity of the square order.From the bottom up may be

Implement hollow triangle and hollow triangle
Background: A project has a tab switch that requires the effect of a hollow triangle. As a back-end engineer, I really don't know how to write it. I found some implementation methods on the Internet and found that most of them are solid triangles. Later, I finally found a hollow t
Draw a triangle arrow pattern with pure CCS and draw a triangle with ccs
Draw a triangle arrow with CSS. With pure CSS, you only need a small amount of code to create triangle arrows compatible with various browsers!

[Unicode] character encoding table information, unicode character encoding
The UTF-8 is somewhat similar to the Haffman encoding, which encodes Unicode:
0x00-0x7F characters, expressed in a single byte;
The character 0x80-0x7FF is expressed in two bytes;
0x800-0xFFFF characters are represented in 3 bytes;
① The unicode
