+% |loc_to_scr| gets the locale form a script range (note the locale is
+% the key, and that there is an intermediate table built on the fly for
+% optimization). This locale is then used to get the |\language| and
+% the |\localeid| as stored in |locale_props|, as well as the font (as
+% requested). In the latter table a key starting with |/| maps the font
+% from the global one (the key) to the local one (the value). Maths are
+% skipped and discretionaries are handled in a special way.
