Using [[LuaTeX]] as the processing engine in ConTeXt allows one to directly use fonts installed on the user's system. Instead of converting all fonts into the standard <code>.tfm</code> and <code>.vf</code> formats (as outlined in some [[This Way - My Way#MyWay|My Way]] documents<ref>[http://dl.contextgarden.net/websitesarchive/atl/tex/OpenType.pdf OpenType in ConTeXt] by Adam Lindsay</ref><ref>[http://dl.contextgarden.net/myway/expertfonts.pdf Installing Expert Fonts: Minion Pro] by Idris Samawi Hamid</ref>), LuaTeX creates these metric files automatically at run-time. This greatly simplifies font installation in ConTeXt.

This normally only happens for fonts that are still in development like [[TeX Gyre- Old Content]] and [[Latin Modern]].

You need to add the command {{cmd|checkcharactersinfont}} or(better) {{cmd|enabletrackers|[http://context.aanhet.net/svn/contextman/context-reference/en/co-fonts.pdf The new manual chapter on fontsmissing]}} in the preambleof your document.

After that, using the all you have to do is search for <code>simplefontsstart missing characters:</code> module;* in the standard way, using [[TypeScripts]]log file.

It simplifies the use of fonts in LuaTeX by<context source="yes">* freeing the user from writing or using \enabledirectives[logs.errors=missing characters]\mainlanguage[TypeScriptsagr]\replacemissingcharacters\startTEXpage[offset=2em];* offering an interface similar to the [http://www.ctan.org/tex\input aristotle-archivegrc\stopTEXpage</macros/xetex/latex/fontspec/ fontspec package for XeTeX]context>

For instance, assuming This particular error quits ConTeXt after the [http://wwwfirst run.josbuivenga.demon.nl/delicious.html Delicious fonts] The last two lines in the console are properly installed and recognized by ConTeXt, you can simply write:

<texcodepre>system > status > quitting due to: missing characters\usemodule[simplefonts] % load the module\setmainfont[Delicious] % set Delicious as main (serif) fontmtx-context | fatal error: return code: 1</pre>

* If you're using Handling fonts in LuaTeX along with TeXlive 2009, <code>simplefonts</code> is already installedcan be done* If you're running in a simple but limited way, using the [[ConTeXt Standalone]], Simplefonts - Old Content|<code>simplefonts</code> can be installed like [http://wiki.contextgarden.net/ConTeXt_Standalone#Installing_third_party_modules any third-party module]:]; first* in the standard way, using [[TypeScripts -setup.sh --extras="t-simplefonts"Old Content]]

<{{cmd>|usetypescriptfile</cmd> }} is the preferred command because it takes care of the<{{cmd>|starttypescriptcollection</cmd>}}/<{{cmd>|stoptypescriptcollection</cmd> }} environments.

Each of the typescripts below defines a keyword to use with <{{cmd>|setupbodyfont</cmd>}}. Usually this is the same as the name of the typescript, but there is one exception (<code>antykwa-torunska</code>)

* Antykwa Toruńska (ts name: <code>antykwa-torunska</code>; only serif; defines <tt>antykwa</tt> as keyword for <{{cmd>|setupbodyfont</cmd>}})

But ... how is it any different, then? Well, the difference is that in Mark IV, we can use an Opentype font directly, so that what is done here: when we want to use Palatino, the [[TeX Gyre- Old Content]] equivalent (“Pagella”) is called and we can use its Opentype “features”; read on.
