+ * How to add a new \ref libusb_strerror() translation:
+ * <ol>
+ * <li> Download the latest \c strerror.c from:<br>
+ * https://raw.github.com/libusb/libusb/master/libusb/sterror.c </li>
+ * <li> Open the file in an UTF-8 capable editor </li>
+ * <li> Add the 2 letter <a href="http://en.wikipedia.org/wiki/List_of_ISO_639-1_codes">ISO 639-1</a>
+ * code for your locale at the end of \c usbi_locale_supported[]<br>
+ * Eg. for Chinese, you would add "zh" so that:
+ * \code... usbi_locale_supported[] = { "en", "nl", "fr" };\endcode
+ * becomes:
+ * \code... usbi_locale_supported[] = { "en", "nl", "fr", "zh" };\endcode </li>
+ * <li> Copy the <tt>{ / * English (en) * / ... }</tt> section and add it at the end of \c usbi_localized_errors<br>
+ * Eg. for Chinese, the last section of \c usbi_localized_errors could look like:
+ * \code
+ * }, { / * Chinese (zh) * /
+ * "Success",
+ * ...
+ * "Other error",
+ * }
+ * };\endcode </li>
+ * <li> Translate each of the English messages from the section you copied into your language </li>
+ * <li> Save the file (in UTF-8 format) and send it to \c libusb-devel\@lists.sourceforge.net </li>
+ * </ol>

+ *
+ * This takes a locale string in the default setlocale format: lang[-region]

+ * used, and only 2 letter ISO 639-1 codes are accepted for it, such as "de".
+ * The optional region, country_region or codeset parts are ignored. This
+ * means that functions which return translatable strings will NOT honor the

+ * All strings returned are encoded as UTF-8 strings.
+ *
+ * If libusb_setlocale() is not called, all messages will be in English.
+ *
+ * The following functions return translatable strings: libusb_strerror().
+ * Note that the libusb log messages controlled through libusb_set_debug()
+ * are not translated, they are always in English.
+ *
+ * For POSIX UTF-8 environments if you want libusb to follow the standard
+ * locale settings, call libusb_setlocale(setlocale(LC_MESSAGES, NULL)),
+ * after your app has done its locale setup.
