用Ruby（IRB）打印CP850编码的字符串 [英] Printing a CP850 encoded string with Ruby (IRB)

问题描述

我想打开包含阿拉伯文字（其编码为CP850）的文本文件（test.txt），然后将其内容打印到STDOUT中：

I want to open a text file (test.txt) that contains arabic text (its encoding is CP850), then print its content to STDOUT :

# coding : CP850
STDOUT.set_encoding(Encoding::CP850); # not sure if it's necessary
open('G:/test.txt',?r){|f|
    f.read.each_char{|c| print c};
    # or puts f.read;
}
gets

但它不打印阿拉伯字符，输出是一些符号和随机字符。
使用Ruby 2.2.3

but it does not print the arabic characters, the output is some symbols and random characters. Using Ruby 2.2.3

推荐答案

将文件的编码更改为utf-8。

Change the encoding of the file to utf-8.

我不知道Ruby是如何实现的，但Django（使用Python 3的较新版本），它是：

I don't know how this is accomplished in Ruby, but Django (the newer ones using Python 3), it's:

open('filename.txt', w, 'utf-8)

如果您使用的是Python 2，那将会更加困难。如果是这样，值得升级到3，因为它是原生的unicode，并做任何事情与阿拉伯语很容易。

If you're using Python 2 it will be slightly more difficult. If so, it's worth upgrading to 3 just because it's native unicode and makes doing anything with Arabic a lot easier.
