问题描述

如何将具有阿拉伯语/波斯语数字的一些字符串转换为英文？

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

喜欢我有：

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

有没有任何函数将其编码为英文，如果字符串包含这样的数字，就像最终结果一样转换为：

Is there any function to encode it to english, and if the string contain such number to convert it like end results will be :

str1 = "1212"
str2 = "1212"
str3 = "some string that contains persian digits like 12"

谢谢

推荐答案

对于这些一个转换， tr -method非常方便快捷。它在 tr！中有一个突变的对应物

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"
