I am trying to decode a string I took from file:

file = open ("./Downloads/lamp-post.csv", 'r')
data = file.readlines()
data[0]

'\xff\xfeK\x00e\x00y\x00w\x00o\x00r\x00d\x00\t\x00C\x00o\x00m\x00p\x00e\x00t\x00i\x00t\x00i\x00o\x00n\x00\t\x00G\x00l\x00o\x00b\x00a\x00l\x00 \x00M\x00o\x00n\x00t\x00h\x00l\x00y\x00 \x00S\x00e\x00a\x00r\x00c\x00h\x00e\x00s\x00\t\x00D\x00e\x00c\x00 \x002\x000\x001\x000\x00\t\x00N\x00o\x00v\x00 \x002\x000\x001\x000\x00\t\x00O\x00c\x00t\x00 \x002\x000\x001\x000\x00\t\x00S\x00e\x00p\x00 \x002\x000\x001\x000\x00\t\x00A\x00u\x00g\x00 \x002\x000\x001\x000\x00\t\x00J\x00u\x00l\x00 \x002\x000\x001\x000\x00\t\x00J\x00u\x00n\x00 \x002\x000\x001\x000\x00\t\x00M\x00a\x00y\x00 \x002\x000\x001\x000\x00\t\x00A\x00p\x00r\x00 \x002\x000\x001\x000\x00\t\x00M\x00a\x00r\x00 \x002\x000\x001\x000\x00\t\x00F\x00e\x00b\x00 \x002\x000\x001\x000\x00\t\x00J\x00a\x00n\x00 \x002\x000\x001\x000\x00\t\x00A\x00d\x00 \x00s\x00h\x00a\x00r\x00e\x00\t\x00S\x00e\x00a\x00r\x00c\x00h\x00 \x00s\x00h\x00a\x00r\x00e\x00\t\x00E\x00s\x00t\x00i\x00m\x00a\x00t\x00e\x00d\x00 \x00A\x00v\x00g\x00.\x00 \x00C\x00P\x00C\x00\t\x00E\x00x\x00t\x00r\x00a\x00c\x00t\x00e\x00d\x00 \x00F\x00r\x00o\x00m\x00 \x00W\x00e\x00b\x00 \x00P\x00a\x00g\x00e\x00\t\x00L\x00o\x00c\x00a\x00l\x00 \x00M\x00o\x00n\x00t\x00h\x00l\x00y\x00 \x00S\x00e\x00a\x00r\x00c\x00h\x00e\x00s\x00\n'

Adding ignore do not really help...:

How do you handle Unicode errors?

The Python "SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position" occurs when we have an unescaped backslash character in a path. To solve the error, prefix the path with r to mark it as a raw string, e.g. r'C:\Users\Bob\Desktop\example.

Can Python handle Unicode?

Python's string type uses the Unicode Standard for representing characters, which lets Python programs work with all these different possible characters. Unicode (https://www.unicode.org/) is a specification that aims to list every character used by human languages and give each character its own unique code.

How do I fix Unicodeescape?

We can solve the issue by escaping the single backslash with a double backslash or prefixing the string with 'r,' which converts it into a raw string. Alternatively, we can replace the backslash with a forward slash.

This looks like UTF-16 data. So try

data[0].rstrip("\n").decode("utf-16")

Edit (for your update): Try to decode the whole file at once, that is

data = open(...).read()
data.decode("utf-16")

The problem is that the line breaks in UTF-16 are "\n\x00", but using readlines() will split at the "\n", leaving the "\x00" character for the next line.
