Convert UTF-16 to UTF-8 and remove BOM in python?

Convert UTF-16 to UTF-8 and remove BOM in python?

You can convert a UTF-16 encoded string to UTF-8 and remove the Byte Order Mark (BOM) in Python using the codecs module. Here's a step-by-step guide on how to do this:

import codecs

# Input UTF-16 encoded string (with BOM)
utf16_string = b'\xff\xfeH\x00e\x00l\x00l\x00o\x00,\x00 \x00W\x00o\x00r\x00l\x00d\x00'

# Remove the BOM and decode the UTF-16 string
utf16_string_no_bom = utf16_string[2:]  # Remove the first two bytes (BOM)
utf8_string = utf16_string_no_bom.decode('utf-16le')  # 'utf-16le' stands for little-endian UTF-16

# Convert to UTF-8
utf8_bytes = utf8_string.encode('utf-8')

# Now utf8_bytes contains the UTF-8 encoded string without the BOM
print(utf8_bytes.decode('utf-8'))  # Output: 'Hello, World'

In this code:

  1. We start with an example UTF-16 encoded string utf16_string that contains a BOM.

  2. We remove the BOM by slicing the first two bytes from the utf16_string.

  3. We then decode the remaining UTF-16 encoded bytes using the 'utf-16le' encoding, which is for little-endian UTF-16 (common on Windows systems).

  4. Finally, we encode the resulting UTF-16 decoded string to UTF-8 to get utf8_bytes, which contains the UTF-8 encoded string without the BOM.

Now, utf8_bytes contains the UTF-8 encoded string without the BOM, and you can use it as needed.
