442  Symbol font in some documents is 'StarSymbol; Arial Unicode MS', and Windows

444  has unusually high external leading. So just reset external leading for fonts
445  which are used to bullets, as those should not be used on multiple lines anyway,
446  so in correct rendering external leading should be irrelevant anyway.
