------- Comment #9 from sebor at roguewave dot com 2008-01-11 05:44 ------- I don't agree that localeconv()->grouping is garbage just because thousands_sep is NUL. I'm not aware of anything in C or POSIX that says that. In the case of bg_BG, the grouping is clearly correct. What's questionable in this case is the value of thousands_sep. But that's probably just a bug in the Bulgarian locale definition. Bugs aside, there may be a perfectly valid locale (a user-defined one) in which there is no thsousands_sep (i.e., it's NUL) but where grouping is non-empty. It's trivial to create one as an exercise. The C++ library numpunct should be able to represent such a locale without change.
