[snip]<br>
This line:<div class="im"><br>
<br>
l.p("premier message de Log à accents")<br>
<br></div>
passes a bytestring to the method, and inside the method, this line:<div class="im"><br>
<br>
unicode_str=u'%s : %s \n' % (date_stamp,msg.encode(self.charset_log,'replace'))<br>
<br></div>
it tries to encode the bytestring to Unicode.<br>
<br>
It's not possible to encode a bytestring, only a Unicode string, so<br>
Python tries to decode the bytestring using the fallback encoding<br>
(ASCII) and then encode the result.<br>
<br>
Unfortunately, the bytestring isn't ASCII (it contains accented<br>
characters), so it can't be decoded as ASCII, hence the exception.<br>
<br>
BTW, it's probably better to forget about cp1252, etc, and use UTF-8<br>
instead, and also to use Unicode wherever possible.<br><font color="#888888">
