If it's a single line string. However, in Python-3 string(text, here string_to_hash) and unicode are two different types. You can read more details here https://www.python.org/dev/peps/pep-0263/. The increased datatype size allows for the use of larger coded character sets. That is it for this Python Unicode to String tutorial. Now, the error message is clear: you can only use bytes, not Python strings (what used to be unicode in Python < 3), so you have to encode the strings with your preferred encoding: utf-32, utf-16, utf-8 or even one of the restricted 8-bit encodings (what some might call codepages). Why is reading lines from stdin much slower in C++ than Python? What 80s childrens fantasy movie has a scene with a court jester who snaps his fingers and disappears? What is the main reason that God created the woman? To solve this problem, we need to add an escape character "\" to convert our ' character to be a normal character, not a superscript of string. read() will always read the whole file - you probably want .read(BLOCKSIZE), where BLOCKSIZE is some suitable amount to read/write at once. However, the manual approach is not recommended. Normal form C (NFC) first applies a canonical decomposition, then composes pre-combined characters again. UTF is just an algorithm that turns Unicode into bytes and read it back.
