[reportlab-users] single font for document

[Something Special]

Hello,
  how to globally(for current pdf only) set reportlab to use my font?

I mean, to allow encodings:

from reportlab.pdfbase import pdfmetrics
from reportlab.pdfbase.ttfonts import TTFont
from reportlab.lib.fonts import addMapping

pdfmetrics.registerFont(TTFont('Times',   'Times.ttf'))
pdfmetrics.registerFont(TTFont('TimesI',  'TimesI.TTF'))
pdfmetrics.registerFont(TTFont('TimesB',  'TimesBD.TTF'))
pdfmetrics.registerFont(TTFont('TimesBI', 'TimesBI.TTF'))

addMapping('Times', 0, 0, 'Times')
addMapping('Times', 0, 1, 'TimesI')
addMapping('Times', 1, 0, 'TimesB')
addMapping('Times', 1, 1, 'TimesBI')

But this seems to work for Paragraphs only - inside a table it shows
black squares.
