A PrintableString is a restricted character string type in the ASN.1 notation. It is used to describe data that consists only of a specific printable subset of the ASCII character set. According to the ASN.1 Specification of basic notation, [ 1 ] the character set of PrintableString can be expressed as:

The length of a string can also be stored explicitly, for example by prefixing the string with the length as a byte value. This convention is used in many Pascal dialects; as a consequence, some people call such a string a Pascal string or P-string. Storing the string length as byte limits the maximum string length to 255.
[1] [2] In assembly language, labels can be used anywhere an address can (for example, as the operand of a JMP or MOV instruction). [3] Also in Pascal and its derived variations. Some languages, such as Fortran and BASIC, support numeric labels. [4] Labels are also used to identify an entry point into a compiled sequence of statements (e.g ...
For example, the null character (U+0000 NULL) is used in C-programming application environments to indicate the end of a string of characters. In this way, these programs only require a single starting memory address for a string (as opposed to a starting address and a length), since the string ends once the program reads the null character.
In computing and telecommunications, a control character or non-printing character (NPC) is a code point in a character set that does not represent a written character or symbol. They are used as in-band signaling to cause effects other than the addition of a symbol to the text.
A numeric character reference refers to a character by its Universal Character Set/Unicode code point, and a character entity reference refers to a character by a predefined name. A numeric character reference uses the format &#nnnn; or &#xhhhh; where nnnn is the code point in decimal form, and hhhh is the code point in hexadecimal form.
The tool is usually useful for entering special characters. [1] It can be opened via the command-line interface or Run command dialog using the 'charmap' command.. The "Advanced view" check box can be used to inspect the character sets in a font according to different encodings (), including Unicode code ranges, to locate particular characters by their Unicode code point and to search for ...
