kodepunkte

Kodepunkt, also known as a code point, is a fundamental concept in computing and information theory, particularly in the context of character encoding. A code point is a numerical value that represents a specific character in a character set. In Unicode, the most widely used character encoding standard, each code point corresponds to a unique character, including letters, digits, punctuation marks, and symbols from various writing systems around the world.

Code points are typically represented in hexadecimal notation, prefixed with "U+" to indicate that they are Unicode code points. For example, the code point for the letter "A" is U+0041, and the code point for the smiley face emoji is U+1F600. The range of valid code points in Unicode is from U+0000 to U+10FFFF, which allows for a vast number of characters to be represented.

In Unicode, code points are grouped into planes, with the Basic Multilingual Plane (BMP) covering the range from U+0000 to U+FFFF. Code points beyond the BMP are part of supplementary planes, which include characters from less common scripts and symbols. The use of code points enables the consistent representation and interchange of text across different platforms, programming languages, and applications, facilitating global communication and data exchange.
