Problem with os.system()

         I am facing problems while using os.system() of python for
copying a file from source to destination where the file name is in
unicode (multi lingual characters).My python interpreter is trying to
convert them to ascii and is failing. I tried giving unicode string as
input for the function something like:

c = u"copy "+"\""+full_path+"\" "+dest
os.system (c)

where the full_path contains filenames with unicode characters(unicode
data type). I tried searching in google and came to know that UNICODE
support wasn't there for os.system function till python2.3[1].
Currently I am using python2.6 but couldn't find anywhere whether a
support has been provided or not. Can some one suggest me any work
around for this. If I do a manual encoding of the file name to ascii,
it results in loss of data and hence the copy command wouldn't find
the file name.

Traceback (most recent call last):
  File "C:\", line 32, in <module>
    findFile(u"E:\\New Folder")
  File "C:\", line 17, in findFile
  File "C:\", line 17, in findFile
  File "C:\", line 27, in findFile
    os.system (c)
UnicodeEncodeError: 'ascii' codec can't encode characters in position
47-72: ordinal not in range(128)


Thanks in advance,
