Extended encoding character values

A 63 by 63 grid is required to map all 4096 values for extended encoding. Such a grid would be hard to read in an HTML page like this. Therefore it is recommended you set up your own grid using a spreadsheet. A snippet of the required grid is provided below.

To set up a spreadsheet for extended encoding mapping:

1. Create a spreadsheet with a row that has the alphabet in upper case (A-Z), followed by the alphabet in lower case (a-z), followed by 0 to 9 inclusive, followed by a hyphen (-), and a period (.).
2. Create a single column at the left with the same values.
3. Type a zero (0) in Column A:Row A, type a one (1.) has a value of 63. See below for a subset of the required columns.
4. Make Column B:Row A equal to Column B-1 (A):Row A + 64. Copy the cell to the rest of Column B.
5. Copy Column B to all other columns.
6. The last value in the table, Column Period (.):Row Period (.) should have a value of 4095.

To read the table, find the column first - then the row. For example:

• 7 = AH
• 133 = CF
• 3975 = -H
• 4037 = .F
