Therefore it is not prepared to deal with 2292 * operations that produce different results depending on the 2293 * locale, such as printf's formatting of decimal numbers, and 2294 * possibly others. 2295 * 2296 * Since GTK+ calls setlocale() by default -importing the locale 2297 * settings from the environment- we must prevent it from doing so 2298 * using gtk_disable_setlocale(). 2299 * 2300 * QEMU's GTK+ UI, however, _does_ have translations for some of 2301 * the menu items. As a trade-off between a functionally correct 2302 * QEMU and a fully internationalized UI we support importing 2303 * LC_MESSAGES from the environment (see the setlocale() call 2304 * earlier in this file).
