| | Wrapping is only performed at an allowed break point, called a soft wrap |
| | opportunity. In most writing systems, in the absence of hyphenation a soft |
| | wrap opportunity occurs only at word boundaries. However, when the |
| | word-wrap property has a value of break-word, unbreakable "words" may be |
| | broken at an arbitrary point to prevent overflow, while still preserving |
| | grapheme clusters. |

| | When no soft wrap location can be found and break-word is allowed, the last |
| | grapheme cluster boundary that can fully fit within the width will be |
| | selected. |
