But according to "man strlen": "RETURN VALUE: The strlen() function returns the number of bytes in the string pointed to by s.". It says nothing about "number of characters". Yeah - when dealing with Unicode, you have to be very clear about whether you're dealing with bytes, runes or glyphs.

Runes are not a Unicode concept - that’s a Golangism. Basically a code point.

Also in terms of Unicode, graphemes are even more relevant to the programming side than glyphs - unless you’re writing a renderer.
