The previous regular expression used manual surrogate-pair ranges to
match emojis and missed a large category of commonly used symbols:
/[\uD800-\uDBFF][\uDC00-\uDFFF]|\uD83C[\uDC00-\uDFFF]|\uD83D[\uDC00-\uDE4F]/g
This approach only covers emojis encoded as surrogate pairs (U+1F000 –
U+1F4FF range), but silently skips BMP emojis that use a text-
presentation code point followed by the variation selector U+FE0F,
such as ❤️ (U+2764 U+FE0F), ☀️, ✅, ⚡, ⭐, and keycap sequences
like 1️⃣, as well as ZWJ family sequences (👨👩👧👦) and flag sequences.
Replace with the Unicode property escape \p{RGI_Emoji} using the 'v'
(unicodeSets) flag introduced in ES2024. This single pattern covers
every standardised emoji sequence defined by Unicode, including all
the cases above.
