More Locale problems in Lucene
------------------------------

                 Key: LUCENE-1846
                 URL: https://issues.apache.org/jira/browse/LUCENE-1846
             Project: Lucene - Java
          Issue Type: Bug
          Components: Other
            Reporter: Uwe Schindler
            Assignee: Uwe Schindler
            Priority: Trivial
             Fix For: 2.9


This is a followup to LUCENE-1836: I found some more Locale problems in Lucene with Date Formats.
Even for simple date formats only consisting of numbers (like ISO dates), you should always
give the US locale. Because the dates in DateTools should sort according to String.compare(),
it is important, that the decimal digits are western ones. In some strange locales, this may
be different. Whenever you want to format dates for internal formats you exspect to behave
somehow, you should at least set the locale to US, which uses ASCII. Dates entered by users
and displayed to users, should be formatted according to the default or a custom specified
locale.
I also looked for DecimalFormat (especially used for padding numbers), but found no problems.
