Issue with fonts open paths (fonttools ?)

[bettina comte]

Hello everyone,

I'm trying to draw single line font in drawbot as shown in the following example.

# draw text
fill(1)
rect(0,0,1000,1000)

B = BezierPath()
B.text('d', font='Hairline02-Regular',fontSize=400,offset=(180,200))
fill(None)
strokeWidth(10)
stroke(0,1,0)

drawPath(B)

I've highlighted in red a line that is automatically added by Drawbot (see here).
With some investigation, I suspect that it is caused by fonttools (see here).

Do you have an idea of how this can be fixed ?

Thanks a lot!
