¹ Georgia and Trebuchet MS are bundled with Windows 2000/XP and they are also included in the IE font pack (and bundled with other MS applications), so they are quite common in Windows 98 systems.

² Symbolic fonts are only displayed in Internet Explorer, in other browsers a font substitute is used instead (although the Symbol font does work in Opera and the Webdings works in Safari).

³ Book Antiqua is almost exactly the same font that Palatino Linotype, Palatino Linotype is included in Windows 2000/XP while Book Antiqua was bundled with Windows 98.

⁴ These fonts are not TrueType fonts but bitmap fonts, so they won't look well when using some font sizes (they are designed for 8, 10, 12, 14, 18 and 24 point sizes at 96 DPI).

⁵ These fonts work in Safari but only when using the normal font style, and not with bold or italic styles. Comic Sans MS works in bold but not in italic. Other Mac browsers seems to emulate properly the styles not provided by the font.

⁶ These fonts are present in Mac OS X only if Classic is installed (thanks to Julian Gonggrijp for the corrections).
