To modify this table:
Click the cell that represents the value that you want to change.
For example, to change the value for the hexadecimal number 57, you would click the cell at the intersection of row 50 and column 7.
Type the hexadecimal value of the character to use. (The new value overwrites the existing value.)
The cursor automatically moves to the next cell to the right.
Repeat steps 1 and 2 until you have made all the desired changes.
