What kind of keyboard layout can type ISO 8859-1 characters?
Example of what needs to be typed are (raw and formatted):
Ánam àbìa èbèa Ógbuá
Ánam àbìa èbèa Ógbuá
First of all: Keyboard layouts and character sets are not directly tied to each other. If I type Ü on my keyboard while in a UTF-8 application, the resulting character will be
a UTF-8 character. If I type it in a ISO-8859-1 application, it will be a character from that character set.
That said, there isn't a keyboard layout that covers all ISO-8859-1 characters; every country layout covers a part of them.
According to Wikipedia, ISO-8859-1 covers the following languages' special characters in full:
Afrikaans, Albanian, Basque, Breton, Catalan, English (UK and US), Faroese, Galician, German, Icelandic, Irish, (new - orthography), Italian, Kurdish (The Kurdish Unified Alphabet), Latin (basic classical orthography), Leonese, Luxembourgish (basic classical orthography), Norwegian (Bokmål and Nynorsk), Occitan, Portuguese, Rhaeto-Romanic, Scottish, Gaelic, Spanish, Swahili, Swedish, Walloon
so you can safely assume that the keyboard layouts of those countries cover a part of ISO-8859-1.
