To take advantage of the new rendering engine that Windows utilises these fonts are no longer supported in Office 2013:
- Bitmap
- Printer
- Adobe Type 1
- CFF/Type 2
- TTO
- .FON
If you currently rely on one of these types of Fonts then you may want to visit http://www.freefontconverter.com and try converting them to another Font Type such as TTF (TrueType Font)
