You try to use a font that is not a TrueType font in Microsoft Office Visio 2003. For example, you try to use a font that has an .otf or .ofn extension. However, Visio 2003 does not recognize the font.

Visio 2003 supports only TrueType fonts. TrueType fonts have a .ttf extension. Visio 2003 does not support all the fonts that other Microsoft Office 2003 programs may support.

The Adobe OpenType format is an extension of the TrueType SFNT format that supports Adobe PostScript font data and new typographic features. Adobe OpenType fonts that contain PostScript data have an .otf extension. However, TrueType-based OpenType fonts have a .ttf extension.

Important Consider the following scenario. You have a Visio drawing that was created in an earlier version of Visio. The Visio drawing contains a font that is not a TrueType font. When you open the drawing in Visio 2003, the name of the original font is displayed in the Font box on the toolbar. However, Visio 2003 substitutes the font with the Arial font. The Arial font is a TrueType font. If you want to retain the original font in the Visio drawing, use one of the following methods:

•	Keep a separate copy of the drawing.
•	Do not save the drawing in Visio 2003.

Additionally, printer fonts, bitmap fonts, and PostScript fonts are not supported in Visio 2003. To make sure that most characters in your drawing are displayed without requiring a font substitution, you may want to install a Unicode font to use with Visio 2003.
