in thread perllocale weirdness, bug, or...?

Thank you; indeed, Perl has no guilt.

As I was trying to track down a slightly more complicated issue, I just was on the wrong track for a while.

Looks like _my_ real problem originates from something I now believe to be an en_US.UTF-8 locale/glibc bug or problem which I can reproduce at system level.

Given a simple file having two records with two TAB separated fields each, like
a_2    2
a2     1
a command like 'sort -k 1 | cut -f 1 ' on that file displays
(as if the field delimiter wouldn't work and the second field determines the ordering), whereas on the same file _without_ the second field the sort order is reversed.

This looks like a bug to me, tough I'm not sure yet and don't really know so far whom I should or could report this.
