Answer 1

For these one on one transformations the tr-method is very convenient and fast. It has a mutating counterpart in tr!

#encoding: utf-8

str1 = "١۲١۲"
str2 = "12١۲"
str3 = "some string that contains persian digits like ١۲"

[str1, str2, str3].each{|str| str.tr!('۰١۲۳۴۵۶۷۸۹','0123456789')}

p str1, str2, str3
#"1212"
#"1212"
#"some string that contains persian digits like 12"
