string-width does the best job it can, but you cannot hope to get
exact results when using variable-width fonts.  What string-width
returns should be correct on TTY frames, and only an approximation of
GUI frames, when you mix scripts and thus fonts in the same string.

For pixel-level accuracy on display, you must use display 'space' and
'align' properties.
