I'm reading an excel(.xlsx) file (using module Spreadsheet::XLSX) and getting values like : Iron/ Steel.Â
Problem: The characters  and are not (visible) in the excel file. The rightmost character looks like a white space but isn't as I tried the regex /\s+$/ which didn't work.
Please help how I can clean this string. I want only those characters in my string which are on general English keyboards, i.e., A-Z, 0-9, ~!@#$%^&*()_+=- ` ,./';[]\|}{:"?>< etc.
