Unicode reports with ReportLab

Yesterday I've just figured out that OpenERP's default report engine is still unable to create PDF reports with full unicode character support. Only the characters present in the Latin1 encoding are allowed.
This is all because the PDFs are genereated with the old standard Type1 fonts that have only Latin1 characters. The solution is to use TrueType fonts that have proper unicode support.
After browsing the forums and the net for some time I created a blueprint and a wikipage with a possible solution.

    It should be like pdfmetrics.registerFont(TTFont('DejaVuSans', 'DejaVuSans.ttf',enc))
    in one line not just
    'DejaVuSans', 'DejaVuSans.ttf',enc))

    Thank you Dukai. It works like a charm now. May be you could add the missing pdfmetrics.registerFont(TTFont( into the wiki page. I could't see them, or maybe that's just my case :D. Thank you very much.
