Not for all of them.  Normal single-char glyphs are correct:

(string-width "😀")
=> 2

But grapheme clusters are wrong:

(string-width "☺️")
=> 1

Presumably because it doesn't know that it's a cluster?  Because it
computes the width of just the first code point without the variation
selector:

(string-width "☺")
=> 1
