Character Section [Visio 2003 SDK Documentation]
Shows the formatting attributes for the shape's text, such as font, color, text style, case, position relative to the baseline, and point size.
Each character style in a shape has a corresponding row in the Character section as viewed in the ShapeSheet window. The name of the row represents the number of characters the character style applies to.
Text formats can be set in the Text dialog box (Format menu), by applying a text style, or by making an entry in a Character section cell.
