No?! Please if you explain to me > in greater detail! As I said, you have to tell the browser what you're up to. Also, I just checked the link (shame on me), and you're not using UTF-8 at all. You're using some weird Windows-xyz or ISO-8859-xyz Greek codepage from the previous millennium. (which obviously my browser didn't know, it thought you were using ISO-8859-1, because that's what my browser does, which you weren't) So: tripple-check that * your file is <insert encoding here (aka UTF-8)> * Python knows that * the web browser knows that

I'am still pretty confused about the encodings. Please tell me the difference between 3 things. a) Asking Notepad++(my editor) to save all my python scripts as UTF-8 without BOM. b) Using this line '# -*- coding: utf-8 -*-' Isn't this line supposed to tell browser that the contents of this python script as in UTF-8 and to handle it as such? c) print ''' Content-Type: text/html; charset=UTF-8 /n''' Please explain to me as simple as you can because from the time with php and perl encodings not only gave me a hard time but also caused my program to produce internal server errors so i need to understand the differences. ========================= Also in the other problem with the cookie iam trying to set: ========================= if os.environ.get('HTTP_COOKIE') and cookie.has_key('visitor') == 'nikos': #if visitor cookie exist print "Next time i will count you" cookie['visitor'] = ( 'nikos', time() - 1 ) #this cookie will expire now else: print "I wont be counting you any more" cookie['visitor'] = ( 'nikos', time() + 60*60*24*365 ) #this cookie will expire in an year ========================= Why always the code block pertainign to 'else' get exectuted ane never the code of 'if' The idea is who ever runs 'koukos.py' to set/unset himself out of the counter count so i need i way to set/unset the browser cookie! Thanks you!

This tells Python what encoding the text file comprising the source code itself is in. > c) print ''' Content-Type: text/html; charset=UTF-8 /n''' This tells the web browser what encoding the HTML you're sending it is in. Said HTML is output by your Python script and must match the encoding you specify in (c). Unless you have Unicode string literals in the source code itself, (a) and (b) don't matter much. (c) is quite crucial. Cheers, Chris -- http://blog.rebertia.com

To understand the distinctions you have to see who handles which data, and how. a) a text editor takes keystrokes and cut/paste info and other data, and produces a stream of (unicode) characters. It then encodes each of those character into one or more bytes and saves it to a file. You have to tell Notepad++ how to do that encoding. Note that unless it's saving a BOM, there's no clue in the file what encoding it used. b) The python compiler has to interpret the bytes it finds (spec. within string literals and comments), and decode them into unicode for its own work. It uses the 'coding:' comment to decide how to do this. But once the file has been compiled, that comment is totally irrelevant, and ignored. c1) Your python code has to decide how to encode its information when writing to stdout. There are several ways to accomplish that. c2) The browser sees only what was sent to stdout, starting with the "Content-Type..." line. It uses that line to decide how to decode the rest of the stream. Let me reemphasize, the browser does not see any of the python code, or comments. DaveA |
