When I remove the two calls to binmode, the script produces the same output. This is due to the fact that Lingua::EN::NameCase calls use locale. So whereas wind wrote, "It's not going to help you with your special character issue," the truth is, at least on a Microsoft Windows computer with the right code page and regional (i.e., locale) settings, the module does take care of the character encoding for you. Obviously, it's better and safer to be explicit about the character encodings in your Perl script.

The module converts MCCORD to McCord, but it cleverly does not convert MACHIAVELLI to MacHiavelli. Perché no? Because Machiavelli ends with an i, so it rightly surmises it's an Italian name. Nice.

My favorite name in the list is Þorsteinn Gylfason, converted from all lowercase letters, þorsteinn gylfason. (See þorn.info.)
