A code point, codepoint or code position is a particular position in a table, where the position has been assigned a meaning. The table may be one dimensional (a column), two dimensional (like cells in a spreadsheet), three dimensional (sheets in a workbook), etc... in any number of dimensions.
Technically, a code point is a unique position in a quantized n-dimensional space, where the position has been assigned a semantic meaning. The table has discrete (whole) and positive positions (1, 2, 3, 4, but not fractions).
Code points are used in a multitude of formal information processing and telecommunication standards.[1][2] For example ITU-T Recommendation T.35[3] contains a set of country codes for telecommunications equipment (originally fax machines) which allow equipment to indicate its country of manufacture or operation. In T.35, Argentina is represented by the code point 0x07, Canada by 0x20, Gambia by 0x41, etc.
