In Poland we use standard qwerty keyboards with Polish keyboard layout set (called Polish Programmers), you press alt+character to get the special version (like alt+s gives you ś, alt+a gives you ą and so on, the only nonintuitive one is alt+x which is ź, because alt+z is taken by ż). Combine with shift or caps lock for capital versions. No issues.
Out of curiosity, if an average person were to type it in all caps on their computer, would they be able to easily type the diacritics?
