soul

This version is a merge of the original package soul (version 2.5 which contains some small corrections compared to the version 2.4 from 2003) and the soulutf8 which added some support for UTF-8. Namely the input encodings utf8.def from package inputenc and package ucs’s utf8x.def are supported. The original soul package has been renamed to soul-ori and is still loaded. Its documentation is still relevant. [ctan.org/pkg/soul]

这个版本是原始软件包soul（版本2.5，与2003年的版本2.4相比，包含了一些小的修正）和soulutf8的合并，后者增加了对UTF-8的支持。即，输入编码utf8.def来自软件包inputenc，软件包ucs的utf8x.def也得到了支持。原始的soul软件包已经更名为soul-ori，并仍然被加载。其文档仍然适用。 [ctan.org/pkg/soul]
