Normalize a polish L

[Peter Bengtsson]

In UTF8, \u0141 is a capital L with a little dash through it as can be
seen in this image:

I tried this:
>>> import unicodedata
>>> unicodedata.normalize('NFKD', u'\u0141').encode('ascii','ignore')
''

I was hoping it would convert it it 'L' because that's what it
visually looks like. And I've seen it becoming a normal ascii L before
in other programs such as Thunderbird.

I also tried the other forms: 'NFC', 'NFKC', 'NFD', and 'NFKD' but
none of them helped.

What am I doing wrong?
