Get a UTF-8 string?

[jmarshall9120]

I'm trying to use this library to do SRP for AWS cognito. I need to pass everything to the API as UTF-8 string. I've noticed its all encoded this way:

def long_to_bytes(n):
    l = list()
    x = 0
    off = 0
    while x != n:
        b = (n >> off) & 0xFF
        l.append( chr(b) )
        x = x | (b << off)
        off += 8
    l.reverse()
    return six.b(''.join(l))

Any idea how to make this optional, so I can encode as necessary for the API?

I'm afraid I don't quite understand what you're asking. UTF-8 is a binary encoding for string content so when a string is encoded with UTF-8 what you have are raw bytes rather than a string, which is what you want I think. Can you elaborate on what you're trying to do and where you think it's going wrong?
