No, it's 7 code *points*. Regional flags have a complicated encoding 
scheme. Wales' flag is encoded as:

U+1F3F4 WAVING BLACK FLAG
U+E0067 TAG LATIN SMALL LETTER G
U+E0062 TAG LATIN SMALL LETTER B
U+E0077 TAG LATIN SMALL LETTER W
U+E006C TAG LATIN SMALL LETTER L
U+E0073 TAG LATIN SMALL LETTER S
U+E007F CANCEL TAG

Each one requires 4 UTF-8 code units, that is, a total of 28 bytes.

My point was that Unicode is incredibly complicated, and one should just 
use higher-level facilities that know how to do this.

My 2 c,
