Summary: sb_dbexpimp.py barfs on 0xA3 char

Initial Comment:
I've got a problem where I can't export my hammie.db
and re-import it with sb_dbexpimp.py.

The script barfs with "UnicodeDecodeError".

jerry:/etc/spambayes # ~/sb_dbexpimp.py -i -d new.db -f
hammie.db.export
Importing database new.db using file hammie.db.export
Debug: current word: subject%3A%20%A3

Traceback (most recent call last):
  File "/root/broke.py", line 271, in ?
    runImport(dbFN, useDBM, newDBM, flatFN)
  File "/root/broke.py", line 203, in runImport
    word = uunquote(word)
  File "/root/broke.py", line 116, in uunquote
    return unicode(urllib.unquote(s), 'utf-8')
UnicodeDecodeError: 'utf8' codec can't decode byte 0xa3
in position 9: unexpected code byte
jerry:/etc/spambayes #

I added this code to get the debugging output:

def uunquote(s):
    try:
        return unicode(urllib.unquote(s), 'utf-8')
    except UnicodeDecodeError, e:
        print "Debug: current word: %s\n" % s
        raise

jerry:/etc/spambayes # python -V
Python 2.3.3

0xA3 is a GBP currency symbol. The web interface
handles it OK.

I get these results for a word query on "subject: £"

Statistics for 'subject: £'
   Number of spam messages: 0.
   Number of ham messages: 2.
   Probability that a message containing this word is   
   spam: 0.091837.

If you need a copy of the exported (100K) file just ask.
