Introduction of ASCII:
ASCII is the AmericanStandardCodeforInformationInterchange Standard Code is a system of computer coding based on the Latin alphabet, primarily used to display modern English and other Western European languages.
It is the most common standard for information exchange and is equivalent to the international standard ISO/IEC646.ASCII was first published as a standardized type of code in 1967, and last updated in 1986, with a total of 128 characters defined to date.
In computers, all data is stored and computed using binary numbers (because computers use high and low levels to represent 1s and 0s, respectively). For example, the 52 letters (including uppercase) like a, b, c, and d, as well as numbers such as 0, 1, and a few commonly used symbols (e.g., *, #, @, etc.) are also stored using binary numbers in a computer. also use binary numbers to represent;
And the specific use of which binary digits to indicate which symbols, of course, each person can agree on their own set (which is called coding), and everyone if you want to communicate with each other without causing confusion, then we must use the same coding rules, and so the U.S. standardization organizations have introduced the ASCII coding, the unified regulations The ASCII code was introduced by the relevant US standardization organizations to standardize the binary numbers used to represent the commonly used symbols mentioned above.
The American Standard Code for Information Interchange (ASCII) was developed by the American National Standards Institute (AmericanNationalStandardInstitute,ANSI) as a standard single-byte character encoding scheme for text-based data.
It was initially the American National Standard for different computers to communicate with each other as a common compliance with the Western character encoding standard, which was later set as an international standard by the International Organization for Standardization (International Organization for Standardization, ISO), known as the ISO646 standard. It applies to all Latin character alphabets.
What does the regular expression [uD800-uDBFF] match? (Note: no transliteration character “\”)
The 0-u in it means it matches characters encoded between 0 and u. The ASCII code of 0 is 48, and that of u is 117, so it can match any character encoded in the range 48 -117
What is the ASCII code for "you",
An Ascii code is just a character
“you” is a string with no ASCII code.
What are the ascii code values for upper and lower case letters and numbers
SCII (AmericanStandardCodeforInformationInterchange, the American Standard Code for Information Interchange) is a system of computer coding based on the Latin alphabet, primarily used to display modern English and other Western European languages. It is the most common single-byte coding system in use today, and is equivalent to the international standard ISO/IEC646.
