Most things were indeed easy to solve. But this one surprised me. With Python 2.6, I need to outcomment the 'lambda' line. The error is what I get in Python 2.6. It does not matter if I do u"\n".join(het_logboek[i:]). I don't use latin-1 anywhere in my program. I need to convert unicode to bytes in Python 2.6, or else it chokes in the smart quote.


import codecs
import os
import time


def print_log_van_vandaag(logbestand):
    """Print today's log. The Cron Daemon will mail this"""
    vandaag = time.strftime("%Y-%m-%d")
    with codecs.open(logbestand, encoding="utf-8") as logboek:
        het_logboek = logboek.readlines()
        #het_logboek = map(lambda x: x.encode("utf-8"), het_logboek)  # bug in Python 2.6?
        for i, regel in enumerate(het_logboek):
            if regel.startswith(vandaag):
                print os.linesep.join(het_logboek[i:])
                break
Traceback (most recent call last):

print os.linesep.join(het_logboek[i:])
