With few exceptions, all fonts are the same in ReportLab.  Note that the
"font_name" here is the registered name, not the TTF file name. 
Usually, what you want is the "current font":
    w = canvas.stringWidth( "measure this", canvas._fontname,
canvas._fontsize )

I'm not sure where Pier got his code; the canvas.stringWidth method does
not take an "encoding" parameter.
