How to Write Unicode Text to a File Safely?

Converting Unicode Text to a File

When writing Unicode text to a text file, it's important to ensure that the symbols can be used in HTML source. To avoid encoding errors, it's crucial to understand the process and handle Unicode characters correctly.

Rather than converting everything to Unicode and then encoding it, it's better to deal exclusively with Unicode objects as much as possible. When decoding data initially, convert it to Unicode objects. When needed, encode them appropriately before writing.

If your string is a Unicode object, you'll need to convert it to a Unicode-encoded string object before writing it to a file. Here's an example:

foo = u'Δ, Й, ק, ‎ م, ๗, あ, 叶, 葉, and 말.'
f = open('test', 'w')
f.write(foo.encode('utf8'))
f.close()
Copy after login

When reading the file again, you'll get a Unicode-encoded string that you can decode to a Unicode object:

f = file('test', 'r')
print f.read().decode('utf8')
Copy after login

By following these steps, you can safely write Unicode text to a text file and maintain its integrity for use in HTML source.
