I know it. English is not my native language, nor I reside in an English speaking country.
We still have, like all countries in the world, a latinized phonetic version of our words.
And we also can, even if we don't speak english, learn to understand a few words like "COME TO OFFICE", "FIRE ALERT", etc...
You do know, for example, that traffic towers all over the world speak to pilots, whether their country, in English?
Heck, same way people all over the world, not speaking english, nonetheless learn to use all kinds of non-localized app menus that they have to use (they just memorize and contextualize stuff like "File", "Edit", "Save as" etc).
>And yes, pagers that use other encodings do exist.
Sure, but they're not a necessity (as was implied) to use a pager in a non-english country. We got by without those in the past, even in our "not english speaking" countries...
