Have you tried examining your hash using Data::Dumper, to see what's
*really* in it?
use Data::Dumper;
print Dumper(\%hash);

You cannot always trust the output of Data::Dumper when it is printed.
For instance, if I showed you the following output you would say that
the key was an empty string.
$VAR1 = {
'' => 3
};
The key is actually the NUL character (ascii 0). The string
Data::Dumper produced has the NUL character in it, put the display
cannot show it. To force Data::Dumper to do the right thing for the
display you must set $Data::Dumper::Useqq to 1. It will then use
doublequoted strings and escape characters (like \t, \n, \0 etc).
perl -MData::Dumper -e '$Data::Dumper::Useqq = 1;%h = ("\0", 3);print
Dumper(\%h);'
$VAR1 = {
"\0" => 3
};
