How do I get a size of an UTF-8 string in Bytes with Python
For some multi-byte encodings (e.g. utf-16), string.encode will add a Byte Order Mark (BOM) at the start, which is a sequence of special bytes that inform the reader on the byte endianness used. So the length you get is actually len(BOM) + len(encoded_word). If you don't want to count the BOM bytes, you can use either the little-endian version ... Web1 Answer. Sorted by: 5. sys.getsizeof returns the size that the object takes in memory.
