Determining IO layer set on filehandle

Filehandles may have IO layers applied to them, like :utf8 or :raw. One of the ways to achieve that is to use the binmode() function. binmode $fh, ':utf8'; What I want to achieve is to set the STDOUT filehandle to ':raw' and then to restore the previous IO layers. sub out_bin { binmode S
