Class FontSelectorCBC

public class FontSelectorCBC
extends FontSelector

The standard character-by-character font selector. XSL-FO 1.0, Section 7.8.3, described the character-by-character strategy as being "the same as the strategy used to select fonts in CSS." Therefore, the CSS documentation should be consulted. The algorithm for font selection is described in the CSS 2 standard at Section 15.5. Even though there are now versions of CSS past version 2, we still use CSS 2. CSS 2.1 removed the font-stretch property, but XSL-FO 1.1 requires it, so, until given more clear guidance, we use the 2.0 algorithm.
