When the Unicode characters that are visible in a text viewer or editor are not enough and you need to see the byte values of each character of a document you should start the hex viewer that is available on the Tools menu. It has two panels: the characters are rendered in the right panel and the bytes of each character are displayed in the left panel. There is a 1:1 correspondence between the characters and the characters: the bytes of a character are displayed in the same matrix position of the left panel as the position of the character in the matrix of the right panel.
