+     * http://www.boost.org/doc/libs/1_64_0/libs/locale/doc/html/conversions.html
+     *
+     * Characters are made uppercase one by one. This is because, in
+     * static builds, we are using iconv, which is visibly not
+     * supported correctly (TODO: Understand why). Case folding seems
+     * to be working correctly if using the default backend under
+     * Linux (ICU or POSIX?). If one wishes to use case folding, one
+     * would use:
+     *
+     *   boost::locale::generator gen;
+     *   std::locale::global(gen(DEFAULT_LOCALE));
+     *   return boost::locale::to_upper(source);
+     *
+     * (2) The function "boost::algorithm::to_upper_copy" does not
+     * make use of the "std::locale::global()". We therefore create a
+     * global variable "globalLocale_".
+     * 
+     * (3) The variant of "boost::algorithm::to_upper_copy()" that
+     * uses std::string does not work properly. We need to apply it
+     * one wide strings (std::wstring). This explains the two calls to
+     * "utf_to_utf" in order to convert to/from std::wstring.
