R 使用ASCII标题的devtools手动生成

我正在构建一个包，但文档必须是西班牙语，包括波浪形字符（即，í，é）

我在R文件中有一个简单的函数：

#' Función con acénto
#'
#' Permite instalar rápidamente de manera local un paquete previamente descargado
#' @param direccion La dirección del archivo local, poner .zip
#' @keywords FAhorroDS
#' @export
#' @encoding UTF-8
#' @author Eduardo Flores
#' @examples
#' FA_InstalarLocal("paquete_x_1.10.zip")

FA_InstalarLocal<-function(direccion)
{
  install.packages(direccion, repos = NULL, type="source")
}

但是，即使我在这里和文档文件中都指定了编码，当我运行：

system（“R CMD Rd2pdf。--output=manual.pdf--force”）

时，我会得到以下错误：

Hmm ... looks like a package
Converting Rd files to LaTeX Warning: ./man/FA_InstalarLocal.Rd:6: Some input could not be re-encoded to ASCII

当我看到这个包时，描述还可以，但是函数的标题变成了NA

关于为什么所有其他内容（描述中有一个波浪号）都正确编码，但标题没有正确编码，你有什么想法吗

您在描述文件中设置了编码吗？@Thomas是的，我设置了，也设置了UTF-8。您在描述文件中设置了编码吗？@Thomas是的，我设置了，也设置了UTF-8
