I believe this regional symbols vs. text difference can also be seen in many washing machines - it is quite common to have symbols for the knobs and settings here (e.g. https://imgur.com/a/7yRzT), while I've understood that this isn't common in e.g. US.

Though I thought textile care symbols are common in US as well, or at least I think all my US-bought clothes have them too. So this is probably not one of those US-Europe differences.
