Re: UnicodeDecodeError, how to elegantly deal with this?

[Jorgen Bodde]

Hi Edwin,

Filemask is obvious as it is assigned in the python code itself. It is
"%file%". The idea is that the file clicked is substituted for the
"%file%" by the replace action. The file that needs to be substituted
is a simple file on disk.

Here is a dump of the file and it's characters. I do understand that
it is not in the range of ASCII but how can I make it so that it will
work?

I assume it is about this part:

OllieÂŽs Gold.avi

But what can I do to decode that properly?

With regards,

if you can print out values of 'filemask', and 'thefile' variables, whenit crashes, I can help.

thx. Edwin

Subject: UnicodeDecodeError, how to elegantly deal with this?
Hi All,

I am relatively new to python unicode pains and I would like to have
some advice. I have this snippet of code:

def playFile(cmd, args):
argstr = list()
for arg in appcfg.options[appcfg.CFG_PLAYER_ARGS].split():
thefile = args["file"]
filemask = u"%file%"
therep = arg.replace(filemask, thefile) ##### error here
argstr.append(therep)
argstr.insert(0, appcfg.options[appcfg.CFG_PLAYER_PATH])

try:
subprocess.Popen( argstr )
except OSError:
cmd.html = "<h1>Can't play file</h1></br>" + args["file"]
return

cmd.redirect = _getBaseURL("series?cmd_get_series=%i" % args["id"])
cmd.html = ""

-------------------

It crashes on this:

20:03:49: File
"D:\backup\important\src\airs\webserver\webdispatc h.py", line 117, in
playFile therep = arg.replace(filemask, thefile)

20:03:49: UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in
position 93: ordinal not in range(128)

20:03:49: Unhandled Error: <type 'exceptions.UnicodeDecodeError'>:
'ascii' codec can't decode byte 0xc2 in position 93: ordinal not in
range(128)

It chokes on a ` character in a file name. I read this file from disk,
and I would like to play it. However in the replace action it cannot
translate this character. How can I transparently deal with this issue
because in my eyes it is simply replacing a string with a string, and
I do not want to be bothered with unicode problems. I am not sure in
which encoding it is in, but I am not experienced enough to see how I
can solve this

Can anybody guide me to an elegant solution?

Thanks in advance!
- Jorgen
