The C language was designed and implemented by Dennis M. Rit

ASCIIIn a computer, all data is stored and computed using binary numbers (because the computer represents 1 and 0, respectively, with high and low levels), for example, 52 letters (including uppercase) such as a, B, C, D, and 0, 1, and other commonly used symbols (such as *, #, @ And so on in the computer is also used to store the binary number to represent, and specifically which binary numbers to indicate which symbol, of course, everyone can contract their own set (this is called code), and i

Ansi string we are most familiar with, English occupies one byte, Chinese characters 2 bytes, ending with a \ 0, commonly used in txt text files.Unicode string. Each character (Chinese character or English letter) occupies 2 bytes. In the VC ++ world, Microsoft prefers Unicode, such as wchar_t.UTF8 is A form of Unicode compression. English A is expressed as 0x0041 in unicode. In English, this storage method is too wasteful because it wastes 50% of spa

Since the contact programming, has been to the coding knowledge smattering, always has not mastered the essence.For example: the relationship between ANSI and GBK, what is the relationship between GBK and gb2312, what is the difference between ANSI and UTF8, what is the relationship between Unicode and UTF8, and ANSI, GBK, gb2312, UTF8 (with or without BOM), UTF1

ANSI. SYS is a very useful device driver in the MS-DOS, which we can achieve unexpected display. So how should we use it? The following is an introduction. Note: In this section, uppercase letters in the syntax and ANSI escape sequence must be typed as is. ANSI. SYS defines a series of functions that are used to change the display graphics, control cursor movem

If you write programs on windows, I believe you will encounter conversion between Unicode and ANSI strings (string To achieve conversion between Unicode and ANSI, I briefly introduced in a previous article: The vs series cstring to string method. In fact, the methods in this article are not described by me, simple and effective, and I am not very clear about the principle. Most people use the following tw

ANSI escape code, ansiescapecode Recently, I am working on the SSH Terminal Project on iOS. It is mainly to remotely connect to Unix systems on mobile phones and perform some simple commands, similar to SecureCRT; today I want to summarize the new thing encountered in this project-ANSI escape code. Excerpt https://en.wikipedia.org/wiki/ansi_escape_codebrief: in computing,

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

ANSIEscape sequencesAre characters embedded in the text used to control formatting, color, and other output options on video text terminals. almost all terminal emulators designed to show text output from a remote computer, and (portable t for Windows) to show text output from local software, interpret at least some of the ANSI escape sequences. By default what ever you send to console it is printed as its. For e.g. Consider following echo statement,$

I want to convert ANSI encoding to UTF8 encoding to realize code. most of the systems I developed using php run in unix, and all the codes are utf8 (databases and webpages ), however, garbled characters often occur when reading files uploaded by windows, because the file encoding in windows is ansi. This requires conversion. First, I cannot ask the user to switch. Second, calculate the implementation code f
