strings hold characters, not bytes. an encoding is used to convert a stream of characters to a stream of bytes. if you need to know the number of bytes needed to hold an encoded string, you need to know the encoding. (and in some cases, including UTF-8, you need to *do* the encoding before you can tell how many bytes you get) > Is the "len" function the right way of get it? len() on the encoded string, yes. > Laci look the following code: > > import urllib2 > request = urllib2.Request(url= 'http://localhost:6000') > data = 'data to send\n'.encode('utf_8') > request.add_data(data) > request.add_header('content-length', str(len(data))) > request.add_header('content-encoding', 'UTF-8') > file = urllib2.urlopen(request) > > Is always true that "the size of the entity-body" is "len(data)" > independently of the encoding of "data"? your data variable contains bytes, not characters, so the answer is "yes". on the other hand, that add_header line isn't really needed -- if you leave it out, urllib2 will add the content-length header all by itself. </F> -- http://mail.python.org/mailman/listinfo/python-list
