I do not believe this is a good idea. Generally, programs save and load
files in C locale, at least for numerical data. So there is no
compatibility problem. Here is how it works :

char *	old_num_locale =3D g_strdup(setlocale(LC_NUMERIC, NULL));
setlocale(LC_NUMERIC, "C");

/* Here save or load data */

setlocale(LC_NUMERIC, old_num_locale);
g_free(old_num_locale);

Note that this use GLib calls. Probably strdup and free also work.
Sometimes, the time locale must also be changed (if the time of
creation/revision of the file must be saved with the data).

Best regards,

Jean
