Re: Apple has redrawn the poo emoji
"...So, these emoji things are not standardised in terms of appearance?"
Not at all. The Unicode consortium provides charts with example glyphs at
http://www.unicode.org/charts/
Each chart contains boilerplate that says, among other things :
"The shapes of the reference glyphs used in these code charts are not prescriptive. Considerable variation is to be expected in actual fonts."
