/**
|
|
* 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.
