The Offset property specifies the position of the change, the AddedLength property specifies how many symbols were added, and the RemovedLength property specifies how many symbols were removed. When the change occurs in a TextBox, a symbol is a single character. When a change occurs in a RichTextBox, a symbol is one of the following:
An opening or closing tag for a TextElement element.
A UIElement element contained within an InlineUIContainer or BlockUIContainer. Note that such a UIElement is always counted as exactly one symbol; any additional content or elements contained by the UIElement are not counted as symbols.
Each 16-bit Unicode character inside of a text Run element.
