## 子标题

拉丁字母扩展-A只包含两个子标题：欧洲拉丁字母与废弃字母。

### 欧洲拉丁字母

欧洲拉丁字母子标题囊括了拉丁字母扩展-A区块中除了之外的所有字符。它包含了带有附加符号的变体大写和小写拉丁字母，大多数用于书写东欧语言。

### 废弃字母

废弃字母子标题仅包含U+0149，该字符的存在是为了兼容ISO/IEC 6937标准。自5.2.0版本起该字符废弃，其注释为：“U+0149 LATIN SMALL LETTER N PRECEDED BY APOSTROPHE是为了南非语的使用而编码的。该字符已废弃，并强烈建议不使用。”在几乎所有的情况下，用撇号加上“n”来表示此字符更佳（’n）。
