Unfortunately under Microsoft Windows this only gives the 'hardwired'
"UTF-8" encoding:
void prepare_data()
{
...
if(locale_id_.empty()) {
real_id_ = util::get_system_locale(true); // always UTF-8
...
}
...
}
where util::get_system_locale(false) would at least do part of the mapping
from codepage to encoding (see my initial posting).
