'UCS-2' codec can't encode characters in position 1050-1050

When I run my Python code, I get the following errors:

  File "E:\python343\crawler.py", line 31, in <module>
    print (x1)
  File "E:\python343\lib\idlelib\PyShell.py", line 1347, in write
    return self.shell.write(s, self.tags)
UnicodeEncodeError: 'UCS-2' codec can't encode characters in position 1050-1050: Non-BMP character not supported in Tk

Here is my code:

x = g.request('search', {'q' : 'TaylorSwift', 'type' : 'page', 'limit' : 100})['data'][0]['id']

# GET ALL STATUS POST ON PARTICULAR PAGE(X=PAGE ID)
for x1 in g.get_connections(x, 'feed')['data']:
    print (x1)
    for x2 in x1:
        print (x2)
        if(x2[1]=='status'):
            x2['message']

How can I fix this?

Your data contains characters outside of the Basic Multilingual Plane. Emoji's for example, are outside the BMP, and the window system used by IDLE, Tk, cannot handle such characters.

You could use a translation table to map everything outside of the BMP to the replacement character:

import sys
non_bmp_map = dict.fromkeys(range(0x10000, sys.maxunicode + 1), 0xfffd)
print(x.translate(non_bmp_map))

The non_bmp_map maps all codepoints outside the BMP (any codepoint higher than 0xFFFF, all the way up to the highest Unicode codepoint your Python version can handle) to U+FFFD REPLACEMENT CHARACTER:

>>> print('This works outside IDLE! \U0001F44D')
This works outside IDLE! 👍
>>> print('This works in IDLE too! \U0001F44D'.translate(non_bmp_map))
This works in IDLE too! �
