To do this task is not trivial in CMD.EXE, I don't know about PowerShell.
(Boy oh boy, the last time I did a '.BAT' file was in 2013 in AudioScope.sh.)

Here is the method used in CMD.EXE translated to UNIX.
Inside the code are the two main batchfile lines to do the task from decimal to character.

Code:

#!/usr/local/bin/dash
# Quick and dirty convert hex to char to demonstrate the Windows CMD.EXE method.

# Hex value '0x41' is 'A'.
HEXVAL="41"
DECIVAL=$( printf "%d" "0x${HEXVAL}" )
/usr/local/bin/dash -c "exit ${DECIVAL}"
RC=$?
CHAR=$( printf \\$( printf "%o" "${RC}" ) )
echo "${CHAR}"

# REM Windows CMD.EXE "terminal", (might even work in COMMAND.COM for 32 bit Windows).
# REM A starter to get a quick and dirty ASCII character from decimal.
# REM Converting hex to decimal is just a couple of lines away.
# REM Looping through each hex pair should be easy.
#
# CMD.EXE /C EXIT 65
# ECHO %=exitcodeAscii%

Result of the demo, OSX 10.14.3, default bash terminal calling 'dash'.

Code:

(I have actually used the RC method for peeking memory on the AMIGA in Python.)
Have fun...

ps

PS(1)							      General Commands Manual							     PS(1)

NAME

       ps - process status

SYNOPSIS

       ps [-alxU] [kernel mm fs]

OPTIONS

       -a     Print all processes with controlling terminals

       -l     Give long listing

       -x     Include processes without a terminal

EXAMPLES

       ps -axl		   # Print all processes and tasks in long format

DESCRIPTION

       Ps  prints the status of active processes.  Normally only the caller's own processes are listed in short format (the PID, TTY, TIME and CMD
       fields as explained below).  The long listing contains:

	 F  Kernel flags:	    001: free slot	     002: no memory map 	  004: sending; 	   010:  receiving	      020:
       inform on pending signals	   040: pending signals 	  100: being traced.

	 S	 State: 	   R: runnable		 W: waiting (on a message)	     S: sleeping (i.e.,suspended on MM or FS)		Z:
       zombie		T: stopped

	 UID, PID, PPID, PGRP	   The user, process, parent process and process group ID's.

	 SZ	 Size of the process in kilobytes.

	 RECV	   Process/task on which a receiving process is waiting or sleeping.

	 TTY	       Controlling tty for the process.

	 TIME	   Process' cumulative (user + system) execution time.

	 CMD	 Command line arguments of the process.

       The files /dev/{mem,kmem} are used to read the system tables and command line arguments from.  Terminal names in /dev are used to  generate
       the mnemonic names in the TTY column, so ps is independent of terminal naming conventions.
