Ah excellent! This also shows a minor bug by which the upper case 'Z' is not correctly caught above. I think I'll add a bit of code to emit on stderr when in debug mode the header name when this situation happens. I'll see what can be done, and if we can consider adding an option to work around this (at least forcing all names to be lower case). Thanks, Willy
