It is not immediately obvious – at least it wasn’t to me – that this BBC headline* starts with the word ill set in caps in a sans serif font. I wondered why the Roman numeral 3 (III) was appearing in that position.
This image has been copied at the largest magnification size available in Firefox, then using Windows Magnifier. A close examination at this magnification of the mouse pointer over the relevant letters does show that the width of the first letter is indeed very slightly greater than the others.
A similar problem arises with the number 1 in such fonts.
