Punctuation and symbol codes carry the most syntactic weight per byte in programming: a single '$' can change how a parser reads an entire expression. When '$' needs to appear as literal data rather than syntax, you often have to escape it — in string literals, in regular expressions, in URLs (where it becomes %24), or in HTML. Knowing its exact code point (36) helps when you filter, validate, or sanitize input byte by byte.
