\_codedecl \tenrm {Latin Modern fonts (EC) preloaded <2020-01-23>} % loaded in format

% Only few text fonts are preloaded:

\_font\_tenrm=ec-lmr10   % roman text
\_font\_tenbf=ec-lmbx10  % boldface extended
\_font\_tenit=ec-lmri10  % text italic
\_font\_tenbi=ec-lmbxi10 % bold italic
\_font\_tentt=ec-lmtt10  % typewriter
\_tenrm

\_public \tenrm \tenbf \tenit \tenbi \tentt ;

\_endcode %---------------------------------------------------

The format in lua\TeX/ can download only non-Unicode fonts. Latin Modern EC is
loaded here. These fonts are totally unusable in LuaTeX when languages with out
of ASCII or ISO-8859-1 alphabets are used (for example Czech). We load only
a few 8bit fonts here especially for simple testing the format.
But, if the user needs to do more serious work, he/she can
use `\fontfam` macro to load a selected font family of Unicode fonts.

We have a dilemma: when the Unicode fonts cannot be preloaded in the format then the basic
font set can be loaded by `\everyjob`. But why to load a set of fonts at the
beginning of every job when it is highly likely that the user will
load something completely different. Our decision is: there is a basic 8bit
font set in the format (for testing purposes only) and the user should load
a Unicode font family at beginning of the document.

The fonts selectors \`\tenrm`, \`\tenbf`, \`\tenit`, \`\tenbi`, \`\tentt`
are declared as `\public` here but only for backward compatibility. We don't
use them in the Font Selection System. But the protected versions of these
control sequences are used in the Font Selection System.
