% \subsection{Encodings}
%
% Soon to be the default, with a just-in-case check:
% \begin{macrocode}
\bool_if:NF \g_@@_euenc_bool
{
\file_if_exist:nTF {tuenc.def}
{
\cs_if_exist:cF {T@TU}
{
\@@_warning:n {tu-clash}
\DeclareFontEncoding{TU}{}{}
\DeclareFontSubstitution{TU}{lmr}{m}{n}
}
}
{
\@@_warning:n {tu-missing}
\bool_gset_true:N \g_@@_euenc_bool
}
}
\bool_if:NTF \g_@@_euenc_bool
{
%<XE> \tl_gset:Nn \g_fontspec_encoding_tl {EU1}
%<LU> \tl_gset:Nn \g_fontspec_encoding_tl {EU2}
}
{ \tl_gset:Nn \g_fontspec_encoding_tl { TU } }
% \end{macrocode}
%
% \begin{macrocode}
\tl_set:Nn \rmdefault {lmr}
\tl_set:Nn \sfdefault {lmss}
\tl_set:Nn \ttdefault {lmtt}
\RequirePackage[\g_fontspec_encoding_tl]{fontenc}
\tl_set_eq:NN \UTFencname \g_fontspec_encoding_tl % for xunicode if needed
% \end{macrocode}
% To overcome the encoding changing the current font size, but only if a class has been loaded first:
% \begin{macrocode}
\tl_if_in:NnT \@filelist {.cls} { \normalsize }
% \end{macrocode}
% Dealing with a couple of the problems introduced by \pkg{babel}:
% \begin{macrocode}
\tl_set_eq:NN \cyrillicencoding \g_fontspec_encoding_tl
\tl_set_eq:NN \latinencoding \g_fontspec_encoding_tl
\AtBeginDocument
{
\tl_set_eq:NN \cyrillicencoding \g_fontspec_encoding_tl
\tl_set_eq:NN \latinencoding \g_fontspec_encoding_tl
}
% \end{macrocode}
% That latin encoding definition is repeated to suppress font warnings.
% Something to do with \cmd\select@language\ ending up in the \texttt{.aux}
% file which is read at the beginning of the document.
%
% \begin{macrocode}
\bool_if:NT \g_@@_euenc_bool
{
%<LU> \cs_set_eq:NN \fontspec_tmp: \XeTeXpicfile
%<LU> \cs_set:Npn \XeTeXpicfile {}

}
% \end{macrocode}
%
%
% \subsection{Generic functions}
%
% \begin{macro}{\FontspecSetCheckBoolTrue}
% \begin{macro}{\FontspecSetCheckBoolFalse}
% These strange set functions are to simplify returning code from LuaTeX:
% \begin{macrocode}

\cs_new:Npn \FontspecSetCheckBoolFalse { \bool_set_false:N \l_@@_check_bool }

%<debug> \typeout{:::: Leftover:~{#3} }
}
\cs_generate_variant:Nn \@@_keys_set_known:nnN {nx}
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\@@_int_mult_truncate:Nn}
% Missing in expl3, IMO.
% \begin{macrocode}
