+/**
+ * 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.
