在python中编码/解码字符串

Question

I have a function that returns a utf-16 encoded string and I have to include its result into another string by a replace:

string = myfunc()

debug_string = debug_string.replace("$rep$", string)

In my eclipse environment it works fine, but in another environment it gives an error:

UnicodeEncodeError: 'ascii' codec can't encode character u'\xe0' in position 23: ordinal not in range(128)

Do you know what is the possible cause?

Thanks

Answer 1

Your string variable isn't in Unicode? Then you need to explicitly decode sequence of bytes (in UTF-16 encoding) from string (string type) to Unicode object:

u_string = myfunc().decode('utf-16')

debug_string also should be in Unicode.

Answer 2

Try:

string = myfunc()

debug_string = debug_string.replace("$rep$", string).encode('utf-16')

Or:

string = myfunc()

debug_string = debug_string.replace("$rep$", string).decode('utf-16')

Answer 3

If possible, work with unicodes all the way. If you can't change myfunc , at least convert its result to unicode:

string = myfunc().decode('utf-16')

If your debug_string is already unicode, it should not be necessary to change anything else. Otherwise decode it as well using the appropriate codec.
