Code point
Definition of Code point
A code point is the unique integer assigned to a character in an encoding. In ASCII, code point 65 is the letter A. In Unicode, code point U+0041 is also A (same value), while U+1F600 is the grinning face emoji.
Code points are abstract numbers - they say nothing about how many bytes a character takes in storage. Unicode code point U+00E9 (e with acute) takes 2 bytes in UTF-8, 2 bytes in UTF-16, and 4 bytes in UTF-32. The code point is the same in all three. Use our base converter to translate code points between decimal, hex, octal, and binary, or look up any ASCII code point on the full table.
