如何将一些具有阿拉伯/波斯数字的字符串转换为英语?

How can I convert some string that has Arabic/Persian number to English ?

就像我有:

推荐答案

对于这些一对一的转换 tr-method 非常方便快捷.它在 tr!

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"
