[David C. Partridge]

Nope just TWO code points e.g. U+1F1FA: REGIONAL INDICATOR SYMBOL LETTER U) followed by 🇸 (U+1F1F8: REGIONAL INDICATOR SYMBOL LETTER S) for the US flag,

There's no such thing as a UTF-8 "graphic character". Grapheme sequences are treated at a higher level anyhow in Qt, and we have APIs for that (QTextBoundaryFinder, etc.).

And it's not 2. 🏴󠁧󠁢󠁷󠁬󠁳󠁿 is 7 code points.
