-    locales across packages?
+    ICU is "portable, open-source Unicode library with:
+    charset-independent locales (with multiple locales simultaneously
+    supported in same thread; character conversions; formatting/parsing
+    for numbers, currencies, date/time and messages; message catalogs
+    (resources) ; transliteration, collation, normalization, and text
+    boundaries (grapheme, word, line-break))".
+    There is also 'iconv', either from XPG4 or GNU (glibc).
+    iconv is about character set conversions.
+    Either ICU or iconv would be valuable to get integrated
+    into Perl, Configure already probes for libiconv and <iconv.h>.
