我正在尝试为一本使用 Unicode 的书创建一个合适的索引。恰当的，我的意思是索引包含 (i) 适当的条目、子条目和子子条目；(ii) 文本跨度的索引；(iii) 带有可点击页码链接的索引条目；以及 (iv) 索引条目内的某些格式。
我的文档是西班牙语的，使用 Unicode，如上所述。更改这一点是不可能的。我还必须继续使用、和polyglossia包hyperref，因为它们是整本书不可或缺的一部分。因此，删除其中任何一个包都不是解决方案。glossarycleverref
我使用TexLive 2020 中的TexStudiowith 。Xelatex对于索引，我使用imakeidxwith xindy。据我所知，它xindy是仅有的两个 Latex 索引器之一，并且它是唯一可以处理 Unicode 的索引器。我也在使用该seealso软件包，因为它尝试修复没有它时出现的各种问题。
这是 MWE。示例中解释了错误。

This simple example is indexed properly\index{properly}, as people\index{people} expect.
We can also do sub-entries\index{structures!sub-entry} and sub-subentries\index{structures!sub-subentry} just fine.
Sub-entries can also be formatted\index{beautification!formatting@\textit{formatting}} fine.
Index headers can be formatted, with things like italics\index{italics@\textsl{italics}} and boldface\index{boldface@\textbf{boldface}}.
But...
ERROR: Jenny\index{Jenny|textbf} can't be bolded. In the index, no boldface is applied and no page number appears.
ERROR: Joe\index{Joe|textit} can't be italicized, either. An index entrey without italics or even a page number is generated.
ERROR: Poor Peter\index{Peter|see{people}} cannot be indexed as a person with \textit{see}. An empty space between two commas appears in his index entry.
ERROR: Unsurprisingly, Paul\index{Paul|see {people}}, with a space in his \textit{see} command, can't be indexed as a person either. An empty space between two commas appears in his index entry, too.
ERROR: Jen\index{Jen|seealso{people}} also breaks things when we want to \textit{seealso} her. Yet again, and empty space with commas on either side appears in her index entry.
ERROR: Jen\index{Jen|seealso {people}} still breaks things when we try to \textit{seealso} her with a space in the command.
ERROR: And the fail\index{fail|(} is total when we try to index a span of text.\index{fail|)}. This causes an empty index entry (except for a comma), and a compiler error, too.
\printindex

正如 MWE 所示，大多数索引功能都已损坏——索引条目的格式、的使用see、的使用seealso、文本跨度的索引。
如何修复这些错误？
