在 R 包/.Rd 文件中搜索 unicode 字符 [英] Search unicode character in R package/.Rd file

问题描述

如何在 R 包或特定文件中搜索特定的 unicode 字符(我使用的是 RStudio IDE).

How can I search for a specific unicode character in an R package or a specific file (I am using the RStudio IDE).

我正在尝试向 CRAN 提交一个包.所有检查都通过，除了:

I am trying to submit a package to CRAN. All checks pass except for:

W  checking PDF version of manual (49.5s)
   LaTeX errors when creating PDF version.
   This typically indicates Rd problems.
   LaTeX errors found:
   ! Package inputenc Error: Unicode character  (U+008D)
   (inputenc)                not set up for use with LaTeX.

因此，当所有 Rd 文件都编译为一个 pdf 时，似乎存在一个有问题的字符.为了解决这个问题，我需要浏览我所有的 .Rd 文件并找到字符 U+008D，反向换行符).

So when all Rd files are compiled to one pdf there seems to be a problematic character. To fix this I need to go through all my .Rd files and find character U+008D, the reverse line feed character).

由于它是一个鬼鬼祟祟的角色，我不确定 RStudio 编辑器是否显示它.

Since it is sort of a sneaky character, I am not sure if the RStudio editor even displays it.

有什么想法吗?

推荐答案

虽然这不是我问题的直接答案，但我会回答解释错误发生的地方.

Although this is not a direct answer to my question, I'll answer to explain where the error occured.

问题是一个 bibtex 条目.我正在使用 Rdpack 包将 bibtex 条目包含在我的 .Rd 文件.

The problem was a bibtex entry. I'm using the Rdpack package to include bibtex entries in my .Rd files.

其中一个条目有一个 bibtex 不喜欢的符号(一些重音符号).删除 bibtex 文件中的字符修复了它.

One of the entries had a symbol that bibtex didnt like (some accent character). Removing the character in the bibtex file fixed it.
