Japanese Fonts shipped with Windows XP use embedded bitmaps to provide legibility at small sizes on the screen. Windows Presentation Foundation (WPF) does not display these bitmaps but instead renders the outlines. These outlines are not instructed (hinted) for good legibility and the results are poor. Meiryo Collection Version 5.00 has been properly instructed for legibility at 9 point size and above in ClearType environments such as WPF.
