Bidirectional Class - White Space

White Space is a value that indicates a character behaves as a visible or invisible gap for text layout, influencing how adjacent characters and words are separated and aligned. In bidirectional text processing, this value marks characters that do not establish a directional embedding or override, instead remaining neutral so they can take the direction of surrounding strong text, which is crucial for correctly ordering spaces, tabs, and punctuation between left-to-right and right-to-left segments. This neutral behavior ensures that whitespace does not break the logical flow of mixed-direction text and helps maintain consistent spacing when reordering is applied.
