Bidirectional Control - No
No is a specific value indicating that a character has no bidirectional control effect, meaning it does not influence text direction, embedding, or override in the Unicode bidirectional algorithm. This applies to the vast majority of characters, such as letters, digits, punctuation, and symbols, which are treated as neutral or follow the inherent directionality of the surrounding text. For these characters, their visual order is determined solely by their natural category (like left-to-right or right-to-left) and the surrounding context, without any explicit directional commands. In practical terms, a "No" value assures that the character will not alter the reading order or create nesting levels, making it the default and expected state for standard text content.
