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.
