# ConTeXt: Cyrillic letters are not rendered

Okay, a really stupid question. How do I compile my Hello World document with Cyrillic letters? Compiling

\starttext
\startsection[title={Testing ConTeXt}]
This is my {\em first} русский ConTeXt document.
\stopsection
\stoptext


gives

Note that the Russian word just disappeared. The log doesn't contain any warnings or errors.

Searching yields a lot of info about making Cyrillic work in LaTeX, but I haven't found anything for ConTeXt. The Encodings and Regimes page on Context Garden just says

in LuaTeX (MkIV) you can normally forget about font encodings

which is obviously not the case. Any thoughts on this?

ConTeXt version is 2013.84.svn30044-18.5 (context --version shows 2013.04.20 01:15); luatex --version shows This is LuaTeX, Version beta-0.76.0-2015102513 (TeX Live 2013/TeX Live for SUSE Linux) (rev 4627).

• Have you loaded a font containing Cyrillic glyphs? – Joseph Wright May 27 '16 at 16:25
• @JosephWright I'm not sure I did. I've only installed a package named texlive-cyrillic, but didn't add any font loading commands anywhere. – ScumCoder May 27 '16 at 16:31
• Quite old context. – Luigi Scarso May 27 '16 at 23:09
• The default font, Latin modern does not include Cyrillic glyphs. Pick a font that does. – Aditya May 28 '16 at 5:08

You need a font that has Cyrillic glyphs. One such free font is Dejavu. If you have it installed, then the following should work:

\setupbodyfont[dejavu]
\starttext
\startsection[title={Testing ConTeXt}]
This is my {\em first} русский ConTeXt document.
\stopsection
\stoptext


Try

\enabletrackers[fonts.missing]
\starttext
\startsection[title={Testing ConTeXt}]
This is my {\em first} русский ConTeXt document.
\stopsection
\stoptext

• I don't know much about ConTeXt, so why would tracking fonts help? Would it solve the answer? – Werner May 27 '16 at 23:51
• As JosephWright said, it can be that the font used has no ghyphs in that area. In this case the tracker records on the log something like "fonts > checking > char й (U+00439) in font 'LMRoman12-Regular' with id 1: missing" for each glyph missed. – Luigi Scarso May 28 '16 at 4:12
• Okay, and how does it answer the question then? – Werner May 28 '16 at 5:36
• The problem can be a combination of 1) missing glyphs in the font used to typeset the text. The default font depends on the format; 2) bug in the font used 3) bug in the format; 4) bug in the engine. For the examples as in this question, and under the assumption that the content of the log is known by the author, in 99% of cases the format is cont-en with the Latin Modern font and the luatex engine: this font doesn't have the glyphs of the chars (case 1) ) so the answer is a) change the font (as shown by Aditya) or or b) use a font fallaback (as suggested by Henri Menke). (cont.) – Luigi Scarso May 30 '16 at 4:26
• ...by Henri Menke). To cover the rest 1% it's necessary to know at least if the format (which can be different from default cont-en) recognises that there are missing glyphs, (and in cont-en the macro \enabletrackers[fonts.missing] does this) otherwise it can be a bug in the font/format/engine. Of course \enabletrackers[fonts.missing] is also valid in the other 99% of the cases. – Luigi Scarso May 30 '16 at 4:27
