ASCII code tables and characters in C # conversion methods. Table of ASCII CharactersThis table lists the ASCII characters and their decimal, octal and hexadecimal numbers. Characters which appear as names in parentheses (e.g., (NL)) are non-printing. A table of the common non-printing characters appears after this table.Char Dec Oct Hex | Char Dec Oc

Preface: Have been curious about this problem, but has not solved, today I finally understand, thank the big boys of Popular Science turn from: 794604851.ASCIIWe know that inside the computer, all information is ultimately a binary value. Each bits (bit) has 0 and 12 states, so eight bits can combine 256 states, which is called a byte. In other words, a byte can be used to represent 256 different states, each of which corresponds to a symbol, which is 256 symbols, from 00000000 to 11111111.In th

When doing dealspider, you must know the charset of the page, and then convert it into a UTF-8, and finally use the regular expression of glib for matching and search. Curl itself does not provide such a function. Previously, we saw the following in the curl_easy_setopt man Manual: curlopt_conv_to_network, curlopt_conv_from_network, so that the two can be automatically transcoded. Later, we found that they cannot. These two are only used for non-ASCII

The origin of ASCII codeAfter the invention of the computer, in order to represent characters in the computer, people developed an encoding called ASCII code. The ASCII code is represented by 7 bits (bit) in one byte, and the range is 0x00-0x7f a total of 128 characters.Then they suddenly found out that "tabs" were missing if they needed to be printed in tabular
