Changes From ISO-8859-1
| Position | 0xA4 | 0xA6 | 0xA8 | 0xB4 | 0xB8 | 0xBC | 0xBD | 0xBE |
|---|---|---|---|---|---|---|---|---|
| 8859-1 | ¤ | ¦ | ¨ | ´ | ¸ | ¼ | ½ | ¾ |
| 8859-15 | € | Š | š | Ž | ž | Œ | œ | Ÿ |
€ became necessary when the euro was introduced. Š, š, Ž, and ž are used in some loanwords and transliteration of Russian names in Finnish and Estonian typography. Œ and œ are French ligatures, and Ÿ is needed in French all-caps text, as it is present in a few proper names such as the city of l'Haÿ-les-Roses or the poet and writer Pierre Louÿs. As diacritics are frequently dropped in all-caps text in French, a code point for Ÿ wasn't deemed necessary for ISO-8859-1, even though one was given for its lower-case equivalent ÿ (at 0xFF).
