Failed to compile if non-english characters included

[ghost]

What should I change to create a document in a language other than English? Thank you.

[eddelbuettel]

I would suggest the following:

• Look at any other RMarkdown document that does it
• Carry the change over.

I guess that you probably just need to declare a UTF-8 encoding, possibly via %\VignetteEncoding{UTF-8} in the vignette header.

[eddelbuettel]

There is nothing you need to do. Quick loG:

edd@brad:/tmp$ mkdir other-languages
edd@brad:/tmp$ cd other-languages/
edd@brad:/tmp/other-languages$ Rscript -e 'rmarkdown::draft("quickCheck.Rmd", template="pdf", package="pinp", edit=FALSE)'
edd@brad:/tmp/other-languages$ # edits quickCheck.Rmd
edd@brad:/tmp/other-languages$ Rscript -e 'rmarkdown::render("quickCheck.Rmd")'

processing file: quickCheck.Rmd

## Introduction 

Il fait chaud en été à Paris.

Schöne Grüße.

and it just works as is.

Your example with French works indeed. However, If you use Ελληνικά (Greek), you will get an error.

[eddelbuettel]

I very strongly suspect that if you do whatever you need to do to typset Greek (or other) letters via Markdown and then LaTeX, it will just work. We this in the template.tex file:

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}

which means UTF-8 character should be supported. For the rest, i,e., direct input of non latin-1 characters you may need to research how RMarkdown does. There is no fundamental reason why this can't work.

This tex.stackexchange.com post seems relevant. It may after all we a regular LaTeX issue. But we're not taking any features away...
