This is a system font which is specially designed for user interfaces, and it is optimized for ClearType font (which is the default font technology for Windows Vista). The advent of this font has led to certain improvements in Windows OS. Now, users can see texts clearly across different languages. Some people may not understand this software; it is not a typical software app with a GUI. The design of this program is compatible with design goals and Aero principals. However, if ClearType is not enabled on your Windows Vista PC, this font may not be able to function properly.
The standard size of this font is increased up to 9pt. for better layout and readability. Also, it comes with a set of new themed font styles referenced by the Aero theme file. Furthermore, Latin, Greek, and Cyrillic characters are supported by this font, and Microsoft will add more. Other character sets supported by this font include Meiryo (Japanese), Microsoft YaHei (Simplified Chinese), Malgun Gothic (Korean), Gisha (Hebrew), Microsoft JhengHei (Traditional Chinese), Majalla UI (Arabic), and Leelawadee (Thai). This font is clearer and more readable than Microsoft Sans Serif, Tahoma, and Arial. Finally, this font is flexible and user-friendly.
