Word Break - E Modifier

E Modifier is a Word Break class that represents characters used to modify the pronunciation or meaning of a preceding symbol, such as the Arabic combining marks, Hebrew points, and other diacritical signs. These characters are typically non-spacing marks that attach to a base character, and in text segmentation, they combine with the preceding character to form a single grapheme cluster. This means that when breaking text into words or user-perceived units, an E Modifier does not start a new segment on its own; instead, it stays with the base character it follows, ensuring that accented or modified letters remain intact. The value is crucial for correctly handling languages with complex script systems, as it prevents unwanted splits between a letter and its diacritical marks, thereby preserving linguistic meaning and proper rendering in digital text processing.
