To verify category values, each category must be set individually
with @code{setlocale(LC_COLLATE,"")} etc.
+@item
+On Android 5.0 and newer, the default locale (i.e.@: the locale in use when
+@code{setlocale} was not called) is the @code{"C.UTF-8"} locale, not the
+@code{"C"} locale. Additionally, a @code{setlocale} call that is meant to set
+the @code{"C"} or @code{"POSIX"} locale actually sets an equivalent of the
+@code{"C.UTF-8"} locale.
