const text = r"""\u{231A}: ⌚ default emoji presentation character (Emoji_Presentation)
\u{2194}\u{FE0F}: ↔️ default text presentation character rendered as emoji
\u{1F469}: 👩 emoji modifier base (Emoji_Modifier_Base)
\u{1F469}\u{1F3FF}: 👩🏿 emoji modifier base followed by a modifier

/// This is the recommended regular expression to use. It matches all

/// This is the old regular expression, prior to `RGI_Emoji` being

/// forced to render as emoji by a variation selector).
