(unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

This error occurs when Python tries to decode a string containing Unicode escape sequences, but the escape sequences are incomplete or invalid. The "\U" escape sequence is used to represent a Unicode character by its code point, followed by 8 hexadecimal digits.

For example, "\U0001F600" represents the "grinning face" emoji.

If the error message specifies a specific position in the string, it means that the "\U" escape sequence at that position is truncated or invalid. To fix the error, you can either correct the escape sequence or use a different encoding method, such as the "\u" escape sequence for shorter Unicode characters or the "chr()" function for numerical Unicode code points.

For example, you can represent the "grinning face" emoji as "\U0001F600", "\uD83D\uDE00", or "chr(128512)".
