[reportlab-users] nbsp and justification problem

[Anton Petrushenkov]

Finally, I've found right spot for simple patch. Suppose it's not very
helpful for better performance, but it still makes work done.

After line 324 in paragraphs.py (def _justifyDrawParaLineX):

# Taking NBSP into account
for word in line.words:
      if word.text.count(u'\u00A0'):
          nSpaces += word.text.count(u'\u00A0')

Suppose it should be included somehow in future releases, but it's up to you
folks.
Thanks for your help.
