But it is the same Latin 'A' just like '0' is the same digit 
(which may look like an O) only it's pronounced differently.

Some languages use pictograms for words instead of letters, like 
Chinese, but whether or not they are encoded with different code 
points for each language idk. Also Chinese has traditional and 
simplified - so, multiple code points for the same word?

My understanding of Unicode has always been that it's merely a 
mapping of a number, a code point, to a letter, word, symbol, 
icon, an idea and nothing more. Unicode is agnostic to layout. 
That's defined in a font.
