Icons, but not text, can be language agnostic and probably more resilient to cultural variation. Obviously well-recognized icons like arrows fit this property more so than time and culturally dependent things like floppy disks for save buttons.
no mention of i18n, no language variation. just try using labels with a more verbose language like german. welcome to hell.
a good icon works across cultures and languages, allows optimized and pixel-perfect UI.
Cancel becomes what, "Zurücksetzen"? "Abbrechen"? All longer strings, good luck with your tiny button.
Not even mentioning Mandarin or Japanese yet.
Oder aber das ist einfach Enterprise-Software Problematik und die Consumer-App Afferl spielen weiter mit ihren Zehen.
