Converting unicode string into usable unicode in Python

Question

I have a database of Unicode strings for emoji such as U0001F60A. I want to pull them from the database and convert them into actual usable unicode strings. (So they appear as emoji and not a bunch of characters.) The standard form seems to be u'\U0001F60A', however, I cannot get this form.

if sentiment < 0:
    emoji = cursor.execute("SELECT emojiuni FROM emojineg WHERE id='{}';".format(num)) # Get negative emoji from DB.
    emoji = cursor.fetchone()
    emoji = emoji[0]

This makes emoji = U0001F60A but I can't append it to u'\ trying variations like

`"u'\" + emoji + "'"`
u' + "\" + emoji + "'"
u'\emoji

Don't work, because u' seems to be a protected command. Is there a way to make the strings into unicode characters, along the lines of the encode() command? (I've tried that also, but that doesn't seem to work, but maybe I'm not doing it right.) Any help is greatly appreciated.

*"I cannot for the life of me get this form"* - Less, please. — Pedro Lobito, Apr 22 '17 at 13:53

2.x:

>>> print unichr(int('U0001F60A'[1:], 16))

3.x:

>>> print(chr(int('U0001F60A'[1:], 16)))

`UnicodeEncodeError: 'UCS-2' codec can't encode character '\U0001f60a' in position 0: Non-BMP character not supported in Tk` ?? – frederick99 Apr 22 '17 at 14:00
@frederick99: Yup. Tk is terrible that way. – Ignacio Vazquez-Abrams Apr 22 '17 at 14:02
Wait. I'm on python 3! – frederick99 Apr 22 '17 at 14:03
@frederick99: ah, [How to print non-BMP Unicode characters in Tkinter (e.g. )](//stackoverflow.com/q/23530080) then. There are a [series of bugs open on IDLE and non-BMP codepoints](https://www.google.co.uk/webhp#q=idle+non-bmp+site:bugs.python.org). – Martijn Pieters Apr 22 '17 at 14:04
This is not related to the question or the answer. Why does `print('ab\b')` print `ab*` in IDLE instead of just `a`? (`*`:a square character) – frederick99 Apr 22 '17 at 14:07
@frederick99: Because `"\b"` is a single non-printable character, but Tk interprets it differently than the terminal. – Ignacio Vazquez-Abrams Apr 22 '17 at 14:09
