         * Quick intro to Unicode in source code:
         * - Every character has a code point (e.g., U+0041 = 'A').
         * - Code points up to U+FFFF use \u1234 (4 hex digits and lowercase u).
         * - Code points above that (up to U+10FFFF) use \U12345678 (8 hex digits and capital letter U).
         * - If your source file is UTF-8, you can type the character directly, but it may not display properly in editors,
         *   and it's harder to see the actual code point.
         * - Some symbols (like many emojis) are built from multiple code points
         *   joined together (e.g., 👋🏻 = U+1F44B + U+1F3FB).
         *
         * Examples:
         *   😍 = "😍" or "\U0001F60D"
         *   👋🏻 = "👋🏻" or "\U0001F44B\U0001F3FB"
         *   🧙‍♂️ = "🧙‍♂️" or "\U0001F9D9\u200D\u2642\U0000FE0F"   (male mage)
         *   🧙🏿‍♀️ = "🧙🏿‍♀️" or "\U0001F9D9\U0001F3FF\u200D\u2640\U0000FE0F" (dark-skinned woman mage)
