Yes Value in Deprecated Unicode Property

Yes is a flag indicating that a character has been officially declared obsolete within the Unicode standard, meaning its use is strongly discouraged for new text. This designation applies to characters that were once encoded but later replaced by other codepoints or encoding schemes, often due to technical flaws or better alternatives. When a character carries this "Yes" value, it signals to software and users that the character is retained only for backward compatibility, not for active use. The presence of this flag does not make the character invalid, but it warns against relying on it in modern text processing, rendering, or data interchange, as future Unicode versions may remove support or alter its behavior.
