I'll trust Peppe's count is thus of bytes in UTF-8.
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.
