How to build with russian language

[istickz]

I add -V option for build:

resume.pdf: resume.md
    pandoc --standalone --template style_chmduquesne.tex \
    --latex-engine=xelatex \
    --from markdown --to context \
    -V papersize=A4 \
    -V lang=russian \
    -o resume.tex resume.md; \
    context resume.tex

But, after building I don't see russian characters in output pdf file.
How to fix this?

I don't know... is this the way to set the language in ConTeXt? (Remember we aren't using LaTeX here)
