预先感谢您的帮助。我正在尝试将RMD文件参数化编织为不同语言的PDF和HTML。亚美尼亚人就是其中之一。编织为HTML总是会产生文字UTF实体，例如<U+0553><U+0578><U+0580><U+0571><U+0561><U+057C><U+0578>。编织LuaLaTeX时，我不断遇到关于找不到armenian.ltf文件的错误提示。
我还尝试使用XeLaTeX并将主字体设置为DejaVu Sans（即latex_engine: xelatex和mainfont: DejaVu Sans，它们确实可以编织，但是所有亚美尼亚语又被编织为UTF实体，而R Markdown给了我错误：
Output created: cv-hy.pdf
Warning messages:
1: LaTeX Warning: Unused global option(s):
[welsh].
2: LaTeX Warning: Unused global option(s):
[armenian].
我不知如何使这项工作有效。任何帮助将不胜感激。
这是我的最小文件（LuaLaTeX）：
---
title: "Test Doc"
author: "Document"
output:
html_fragment:
section_divs: no
pdf_document:
latex_engine: lualatex
geometry: margin = 2cm
params:
lang: yes
lang: "`r switch(params$lang, CY = 'cy-GB', EN = 'en-GB', HY = 'hy-AM')`"
knit: (function(inputFile, encoding){ files <- c("cv-cy", "cv-en", "cv-hy"); langs <- c(list(lang = "CY"), list(lang = "EN"), list(lang = "HY")); i <- 1; for(f in files){ rmarkdown::render(inputFile, output_format = c("html_fragment", "pdf_document"), encoding = encoding, params = langs[i], output_file = c(paste0(dirname(inputFile), "/", print(f)), paste0(dirname(inputFile), "/", print(f)))); i <- i +1 } })
---
```
{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
lswitch <- function(lang, ...){
switch(lang, ..., stop(""))
}
```
`r lswitch(params$lang,
CY = "# Enw",
EN = "# Name",
HY = "# Անում"
)
`
