         <source>&lt;p&gt;These are exceptions to the unac mechanism which, by default, removes all diacritics, and performs canonic decomposition. You can override unaccenting for some characters, depending on your language, and specify additional decompositions, e.g. for ligatures. In each space-separated entry, the first character is the source one, and the rest is the translation.</source>
         <translation>&lt;p&gt;这是针对unac机制的例外，默认情况下，该机制会删除所有的判断信息，并进行正规的分解。妳可以按照自己的语言的特点针对某个字符覆盖掉口音解除设置，以及指定额外的分解（例如，针对复数）。在每个由空格分隔的条目中，第一个字符是源字符，剩下的就是翻译。</translation>
