Writing a hex escaped char in Powershell

问题

Is there any way to write something like this in Powershell? (Linux would be with Perl)

char foo = '\x41';

I need to input some non-printable characters to one of my programs

回答1:

You can do it by casting an int to char.

With a decimal number :

 $foo = (65 -as [char])

And from hexa :

 $foo = (0x41 -as [char])

Both will set $foo to A

回答2:

Short form is:

$foo = [char]0x41
