I am on Windows and using v1.7. I cannot replicate your problem. 
>perl -MFile::Binary -wle"File::Binary->new('>file')->put_ui8(0xa0);"

>debug file
-rcx

Also, I cannot see how it's possible from looking at the source. binmode is getting called.

Could you provide us with a minimal amount of runnable code that give you the problem? Are you sure you're following the instructions?

Will try and set binmode for the handle on if possible (i.e if the object has a binmode method) otherwise you should do it yourself.

IO::Handle objects don't have a binmode method, so you need to call binmode on it before passing the handle to ->new/->open.
