Unless you are specifically declaring and registering a font it will not be used
in reportlab unless it is one of the standard 14. So for example this is from a
Japanese based test and uses msmincho.ttc

> msmincho = TTFont('MS Mincho','msmincho.ttc',subfontIndex=0,asciiReadable=0)
> fn = ' file=msmincho.ttc subfont 0'
> msmincho = TTFont('MS Mincho','msmincho.ttf',asciiReadable=0)
> fn = 'file=msmincho.ttf'
> #Ubuntu - works on Lucid Lynx if xpdf-japanese installed
> msmincho = TTFont('MS Mincho','ttf-japanese-mincho.ttf')
> fn = 'file=msmincho.ttf'
> msmincho = None
> if msmincho is None:
> c.setFont('Helvetica', 12)
> c.drawString(100,600, 'Cannot find msmincho.ttf or msmincho.ttc')
> c.setFont('MS Mincho', 30)
The same could be done for some of the MS fonts eg pmingliu.ttf or simsun.ttf,
but I am certainly no expert here.

I don't believe we are using any specific API to obtain/find fonts.

I know that there is an Asian font pack for Acrobat reader (but that allows the
meta information to be rendered properly). In addition you can always add asian
language support from the windows OS, but which fonts that provides I don't

Ask here, others have certainly faced and overcome these problems
