Unicode and subprocess.Popen

I have a field in a sqlite3 db that contains strings like:

title = "Friedrich_N\u00FCrnberg"

I read this strings in a variable and I want to pass the unicode version of it to a subprocess.Popen call.

The software I am calling through Popen needs to receive as input this:

Friedrich_Nürnberg

instead of this:

Friedrich_N\u00FCrnberg

otherwise the its computation is vain.

This is the calling code:

subprocess.Popen([command, title], stdout=subprocess.PIPE)

How can I modify it?

Thanks a lot.

PS. If I manually try adding a u"" it works, but I cannot use that syntax because I am not explicitly stating the text content of each variable.

That is called a Unicode escape sequence. The desired character you want is called an encoded character.

Here is an example of decoding unicode escape sequences in the Python shell.

>>> title = "Friedrich_N\u00FCrnberg"
>>> character = title.decode("unicode-escape")
>>> character
u'Friedrich_N\xfcrnberg'
>>> print character
Friedrich_Nürnberg

You could try:

title = title.decode("unicode-escape")
subprocess.Popen([command, title], stdout=subprocess.PIPE)

I wrote another answer which I think explains this fairly well. Decoding Unicode in Python
