Where is the unicode?

Question

Using the Python module unicode-nazi to detect unicode issues, I am running into this warning:

/home/dotancohen/unicode-test.py:51: UnicodeWarning: Implicit conversion of unicode to str
print("Here is a phrase: " + str(phrase))

Since phrase is being explicitly cast to string, where is the implicit conversion? Surely "Here is a phrase: " is a string, as it is not preceded by u.

• user395760: I don't know if that's what it complains about, but it sure wouldn't hurt to explicitly encode...
• pylover: phrase.encode('1252')

Answer 1

You need to encode the phrase unicode value explicitly:

print("Here is a phrase: " + phrase.encode('some_codec'))

str() on a unicode value implicitly encodes that value, using the default codec (ASCII on Python 2).

• dotancohen: I see! The warning message should probably say "Implicit encoding of unicode to some_codec in conversion to str". Thank you!
