+\subsection{Selecting scripts}

+Currently \babel{} provides no standard interface to select 
+scripts, because they are best selected with either |\fontencoding|
+(low level) or a language name (high level). Even the Latin script may
+require different encodings (ie, sets of glyphs) depending on the
+language, and therefore such a switch would be in a sense
+incomplete.\footnote{The so-called Unicode fonts does not improve the

+suited for, say, romanization of Indic languages, and the fact it
+contains glyphs for Modern Greek does not mean it includes them for
+Classic Greek. As to directionality, it poses special challenges
+because it also affects individual characters and layout elements.}
