unicode - Python utf-8 handling -

I am using Python 2.6.1 and there is a problem related to UTF-8 with my code. This problem is reproducible with this code:

  # - * - coding: UTF-8 - * - importing OS, system import string, time import codex, again BDATA = '' Domicile lymphobody '' 'Eddie Marson' ',' Isach de Banol ',' 'John Hawks'' print (BDATA) file obz = codex.open ("BTVPreપી 1.txt", "R", "UTF-8") data = File obz. First print of READ () print (data)  

bDATA works fine however, if the same data file is in the BTCPTTP file, Python complains in this way Does:

  cat btvresp2.txt "Domestic Lombardis", "Eddie Marson", "Christian De Banol?" , "John Hawks" Python 2.6.1 (r261: 67515, February 11, 2010, 00:51:29) [GCC 4.2.1 (creation of Apple Inc. 5646)] Darwin type "help", "copyright", "more For information, "Credit" or "License" & gt; & gt; # - * - Coding: UTF-8 - * - ...> gt;> Import OS, sys> & gt; Import code, Time & gt; & gt; & gt; Import codec, RE & gt; & gt; & gt; BDATA = '' Domestic Lombardies' ',' Eddie Marson ',' Isa de Banol ',' John Hawks "" & gt; & gt; Print (BDATA) "Domestic Lombardis", "Eddie Marson", " Isaac D.

 I'm not sure the data read from a file is problem Why do they arise

 It seems The content of your file is not encoded in UTF-8. Are you sure you did not save it in any other encoding? When you do  cat  the file, then the terminal ? Displays  in place of  é , which will also indicate an encoding problem in the file, using your terminal UTF-8. 
 
 Also you have two files,  btvresp1.txt  and  btvresp2.txt . Are you using the right one?
