Trying this.

I do:

from reportlab.pdfgen import canvas
from reportlab.lib.pagesizes import letter
from reportlab.graphics.charts.textlabels import _text2Path

FACE = 'Helvetica'
SIZE = 12

def t(text):
     p = _text2Path(text, 0, 0, FACE, SIZE)
     return text, p.getBounds()

c = canvas.Canvas('_text2Path_test.pdf', pagesize=letter)
print c.getAvailableFonts()
c.setFont(FACE, SIZE)

print t('test')
print t('tegt')
print t('a min')
print t('A min')

I get:

I turned up an old thread on google:

I don't happen to have Acrobat Reader <=5 installed here, so I placed 
the Type1 fonts in the fonts directory of the reportlab package. Is 
there anything better I can do? I'm wondering, what was the "ready 
answer" that Andy had for me?
