kdialog和unicode [英] kdialog and unicode

问题描述

我正在努力让python，unicode和kdialog很好地一起玩。

这是一台linux机器，kdialog是一种在
$ b中生成对话框的方法用户可以与之交互的$ b kde（例如输入文本），你可以在你的脚本中使用输出的文本。


无论如何，我是什么我正在使用

编解码器模块读取utf-8编码的文本文件，并使用以下内容：


data = codecs.open（ ''file''，''r''，''utf-8''）


然后我操纵数据将其分解为文本片段。


然后我运行这个命令：

test = os.popen（'''kdialog --inputbox％s''％（data））

Traceback（最近一次调用最后一次）：

文件" ;< stdin>"，第1行，在？

UnicodeEncodeError：'' ascii''编解码器无法编码字符u''\ u017a''

位置272：序数不在范围内（128）


我真的很喜欢kdialog将文本显示为utf-8。但是，看起来好像是在python尝试将utf-8编码数据传递为ascii，这显然会因为无法处理utf-8而失败。编码文本。是否可以将文本作为utf-8传递给kdialog，而不是ascii？


或者我完全误解了整个过程，其中案件，可以

你请赐教。

只需在传递目标编码之前对其进行编码to os.popen（）：


test = os.popen（''kdialog --inputbox％s''％data.encode（" utf-8"））

是有可能将文本作为utf-8传递给kdialog，而不是ascii吗？

只需将数据编码为目标编码，然后再传递给
os.popen（）：

test = os.popen（''kdialog --inputbox％s''％data.encode（" utf-8"））

>彼得

我曾尝试过，但随后文字看起来像废话。我正在使用

的文本是波兰文，而且

中有很多非英文字符。使用这种方法会产生一些奇怪的字符 - 基本上它

看起来像是用utf-8编码的文件，但使用iso-8859-1显示。


这是我能做的最好的吗？


感谢您的帮助。

我刚刚在我的Suse 9.1上尝试了你描述的设置（使用德语变音符号而不是

波兰语字符），它

Python 2.3和2.4可以正常工作。也许您需要的目标编码不是UTF-8。我想b $ b会尝试其他流行的编码用于波兰语文本（不知道这些是什么...... / b $ b）。 sys.stdout.encoding可能会给你一个线索。

I''m trying to get python, unicode and kdialog to play nicely together.
This is a linux machine, and kdialog is a way to generate dialog boxes in
kde with which users can interact (for example input text), and you can
use the outputted text in your script.

Anyway, what I''m doing is reading from a utf-8 encoded text file using the
codecs module, and using the following:

data = codecs.open(''file'', ''r'', ''utf-8'')

I then manipulate the data to break it down into text snippets.

Then I run this command:

test = os.popen(''kdialog --inputbox %s'' %(data))

Traceback (most recent call last):
File "<stdin>", line 1, in ?
UnicodeEncodeError: ''ascii'' codec can''t encode character u''\u017a'' in
position 272: ordinal not in range(128)

I would really like kdialog display the text as utf-8. However, it seems
that python is trying to pass the utf-8 encoded data as ascii, which
obviously fails because it can''t deal with the utf-8 encoded text. Is it
possible to pass the text out to kdialog as utf-8, rather than ascii?

Or have I completely misunderstood the whole process, in which case, can
you please enlighten me.

Just encode the data in the target encoding before passing it to os.popen():

test = os.popen(''kdialog --inputbox %s'' % data.encode("utf-8"))

I had tried that, but then the text looks like crap. The text I''m using
for this is Polish, and there are a lot of non-English characters in
there. Using this method results in some strange characters - basically it
looks like a file encoded in utf-8, but displayed using iso-8859-1.

Is this the best I can do?

Thanks for your help.

I''ve just tried the setup you described (with German umlauts instead of
Polish characters) on my Suse 9.1, and it works as expected with both
Python 2.3 and 2.4. Perhaps the target encoding you need is not UTF-8. I
would try other popular encodings used for Polish text (no idea what these
are). sys.stdout.encoding might give you a clue.
