ASCII was incorporated into the Unicode (1991) character set as the first 128 symbols, so the 7-bit ASCII characters have the same numeric codes in both sets. This allows UTF-8 to be backward compatible with 7-bit ASCII, as a UTF-8 file containing only ASCII characters is identical to an ASCII file containing the same sequence of characters.
Windows keyboards worldwide tend to simply label the key with the text ↵ Enter, while Apple uses the symbol ⌤ (U+2324 ⌤ UP ARROWHEAD BETWEEN TWO HORIZONTAL BARS [9] or U+2305 ⌅ PROJECTIVE) on ISO and JIS keyboards and the text ⌅ enter on ANSI US keyboards; [10] this is acknowledged by an annotation "enter key" on U+2324 in the Unicode ...
Use a special-character link to enter a Unicode character. Links are available under Special characters above the edit window, and below the buttons at the bottom of the edit window (for more information on the latter, see Help:CharInsert). Clicking a special-character link enters that character at the current position of the cursor in the edit ...
For example, the key labelled "Backspace" typically produces code 8, "Tab" code 9, "Enter" or "Return" code 13 (though some keyboards might produce code 10 for "Enter"). Many keyboards include keys that do not correspond to any ASCII printable or control character, for example cursor control arrows and word processing functions. The associated ...
In HTML and XML, a numeric character reference refers to a character by its Universal Character Set/Unicode code point, and uses the format: &#xhhhh;. or &#nnnn; where the x must be lowercase in XML documents, hhhh is the code point in hexadecimal form, and nnnn is the code point in decimal form.
The C0 and C1 control code or control character sets define control codes for use in text by computer systems that use ASCII and derivatives of ASCII. The codes represent additional information about the text, such as the position of a cursor, an instruction to start a new line, or a message that the text has been received. C0 codes are the ...
In the ASCII standard, the numbers 0-31 and 127 are assigned to control characters, for instance, code point 7 is typed by Ctrl+G. While some (most?) applications would insert a bullet character • (code point 7 on code page 437), some would treat this identical to Ctrl+G which often was a command for the program.

The block contains all the letters and control codes of the ASCII encoding. It ranges from U+0000 to U+007F, contains 128 characters and includes the C0 controls, ASCII punctuation and symbols, ASCII digits, both the uppercase and lowercase of the English alphabet and a control character.
