Python: convert string from UTF-8 to Latin-1
提问by romor
I feel stacked here trying to change encodings with Python 2.5
我觉得这里堆积如山，试图用 Python 2.5 更改编码
I have XML response, which I encode to UTF-8: response.encode('utf-8'). That is fine, but the program which uses this info doesn't like this encoding and I have to convert it to other code page. Real example is that I use ghostscript python module to embed pdfmark data to a PDF file - end result is with wrong characters in Acrobat.
我有 XML 响应，我将其编码为 UTF-8: response.encode('utf-8')。这很好，但是使用此信息的程序不喜欢这种编码，我必须将其转换为其他代码页。真实的例子是我使用 ghostscript python 模块将 pdfmark 数据嵌入到 PDF 文件中 - 最终结果是 Acrobat 中的字符错误。
I've done numerous combinations with .encode()and .decode()between 'utf-8' and 'latin-1' and it drives me crazy as I can't output correct result.
我已经做了无数的组合，带.encode()和.decode()“UTF-8”和“拉丁-1”之间，它让我疯狂，我不能输出正确的结果。
If I output the string to a file with .encode('utf-8')and then convert this file from UTF-8 to CP1252 (aka latin-1) with i.e. iconv.exeand embed the data everything is fine.
如果我将字符串输出到一个文件，.encode('utf-8')然后使用 ie iconv.exe将此文件从 UTF-8 转换为 CP1252（又名 latin-1）并嵌入数据，一切都很好。
Basically can someone help me convert i.e. character áwhich is UTF-8 encoded as hex: C3 A1to latin-1 as hex: E1?
基本上有人可以帮我将 ie 字符á转换为 UTF-8 编码为 hex:C3 A1到 latin-1 as hex:E1吗？
Thanks in advance
提前致谢

Instead of .encode('utf-8'), use .encode('latin-1').
而不是.encode('utf-8')，使用.encode('latin-1')。

data="UTF-8 data"
udata=data.decode("utf-8")
data=udata.encode("latin-1","ignore")
Should do it.
应该做。

Can you provide more details about what you are trying to do? In general, if you have a unicode string, you can use encode to convert it into string with appropriate encoding. Eg:
您能否提供有关您正在尝试做的事情的更多详细信息？一般来说，如果您有一个 unicode 字符串，您可以使用 encode 将其转换为具有适当编码的字符串。例如：
>>> a = u"\u00E1"
>>> type(a)
<type 'unicode'>
>>> a.encode('utf-8')
'\xc3\xa1'
>>> a.encode('latin-1')
'\xe1'

If the previous answers do not solve your problem, check the source of the data that won't print/convert properly.
如果之前的答案不能解决您的问题，请检查无法正确打印/转换的数据来源。
In my case, I was using json.loadon data incorrectly read from file by not using the encoding="utf-8". Trying to de-/encode the resulting string to latin-1just does not help...
就我而言，我json.load通过不使用encoding="utf-8". 试图将结果字符串解码/编码为latin-1只是无济于事......
