------- Additional Comments From julliard@winehq.com 2007-06-03 14:34 ------- It's not really a regression, just a different behavior. Wine used to accept any random locale string that you threw at it, but it now requires the locale to be supported by the C library. That's the only way to ensure proper interoperability between Wine and other Unix libraries.
