Programmatically count characters in documents

The first character in a document is at character position 0, which represents the insertion point. The last character position is equal to the total number of characters in the document. You can determine the number of characters in a document by using the Count property of the Characters collection.

All characters in the document are counted, including spaces, paragraph marks, and other characters that are normally hidden. Even a new, blank document returns a count of one character because it contains a paragraph mark.
