[firebird-python] pack problem in Python 3

[Philippe Makowski]

Hi,

I need your help

this piece of code have no problem under Python2
#coding:utf-8
#
import struct

def addString(codeAsByte, s):
    sLen = len(s)
    format = 'cc%ds' % sLen # like 'cc50s' for a 50-byte string
    newEntry = struct.pack(format, chr(codeAsByte), chr(sLen), s)

def addInt(codeAsByte, value):
    newEntry = struct.pack('ccc', chr(codeAsByte), '\x01', chr(value))

if __name__=='__main__':
    addInt(10,10)
    addString(28,'test'.encode("utf8"))

but under Python3 I get

struct.error: char format requires a bytes object of length 1

for both

any clue ?
