             Bug #: 14039
           Summary: strcoll inverted(?) order of uppercase/lowercase
                    characters
           Product: glibc
           Version: 2.13
            Status: NEW
          Severity: normal
          Priority: P2
         Component: localedata
        AssignedTo: unassigned@sourceware.org
        ReportedBy: ndrwrdck@gmail.com
                CC: libc-locales@sources.redhat.com
    Classification: Unclassified


This is probably invalid, just wanted to raise a potential issue with strcoll.

When sorting ascii characters using their ascii codes 'A' < 'a'. Strcoll does
the opposite 'a' < 'A' and 'Ä' < 'Ä'. The problem with this approach is that,
for performance reasons, a lot of programs use ascii comparison and fall back
on strcoll when they encounter unicode characters. This results in inconsistent
sorting, for example 'A' < 'a' and 'Ä' < 'Ä'.

Should this particular sorting rule be arbitrary, would it be possible to
change it (to match ascii order)?
