universal unicode font for reportlab

[Laszlo Nagy]

I need to create multi lingual invoices from reportlab. I think it is 
possible to use UTF 8 strings but there is a problem with the font. I 
could not find any free TTF font that can do latin1, latin2, arabic, 
chinese and other languages at the same time. Is there a single font 
that is able to handle these languages? (Most of our invoices will be 
for EN, FR, DE, HU, SK, CZ, RO but some of them needs to be in Chinese.)

Thanks,
