Three writing systems of English and localization woes

Did you know there are three different writing systems for English? That’s right - you can write English using letters that aren’t Latin characters. If you’re using KDE Plasma version 6.4 or earlier, go to the “Region & Language” system settings page and search “en_US.” You’ll see two locales in the results, and they both say they’re “en_US.” The latter en_US doesn’t seem to be English at all. It turns out that the “weird” English is the “America English Deseret” locale, and the “normal” en_US is called “America English Latin”.
