in reply to replace multiplication symbol (×)

The star("*") is a special character to a regexp. It means match 0 or more times. To remove the special significance you need to escape it to turn it into text. 

 
for (@input) {s/\×//g};

Another trick is to make it part of a character class 
for (@input) {s/[×]//g};

In this case the things inside the [] are each considered single characters (excpet for maybe a ^ or -) , where any one of them can match a character. In this case [*] is the character class consisting of only *

Sorry, i did "misread to OP's multiplication symbol ("×") as an asterisk ("*")"., guess im getting old

    Sorry I'm confused, why do you identify the characters x and * ?
