⚠️ Technical Notice on Surrogates (Cs):

Technical Classification & Regex Reference

Normative Classification Semantics

In the Unicode Character Database, General_Category is the primary normative classification assigned to every code point. As noted in Unicode Standard Annex #44, this property reflects a character’s primary linguistic or functional usage, but does not capture every contextual use in real-world typography.

Regular Expression Matching

In modern regular expression engines (PCRE, Python, ECMAScript, Java, Rust, .NET), match characters belonging to this category with:

\p{Cs} // Matches any Surrogate
Standards Provenance: Property data derived from the official Unicode Character Database (General_Category (Cs)), Unicode Standard Version 18.0.
