- * This class represents a hyphen. A 'full' hyphen is made of 3 parts:
- * the pre-break text, post-break text and no-break. If no line-break
- * is generated at this position, the no-break text is used, otherwise,
- * pre-break and post-break are used. Typically, pre-break is equal to
- * the hyphen character and the others are empty. However, this general
- * scheme allows support for cases in some languages where words change
- * spelling if they're split across lines, like german's 'backen' which
- * hyphenates 'bak-ken'. BTW, this comes from TeX.
