             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 'ą' < 'Ą'. 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 'ą' < 'Ą'.

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

If you want to approximate strcoll with strcmp you must first convert the
string with strxfrm.
