------- Comment #4 from pcarlini at suse dot de 2008-01-11 02:27 ------- In other terms, on the v3 side, we are not grouping anything in such cases, therefore grouping() can only be the empty string, consistently with 22.2.3.1.2. As for the thousands separator, a '\0' seems a good character as anything else, in that case. I don't see what could v3 do in order to improve the conformance.
