pyfPDF templates and unicode element values?

[Jurgis Pralgauskis]

Hi, 

I tried to combine ideas from http://code.google.com/p/pyfpdf/wiki/Templates

and http://code.google.com/p/pyfpdf/wiki/Unicode

but not much luck... encodings were always hard for me...

I can insert unicode via direct "write" ok, 

but if I try to insert it via cell/multicell, I get stuck ...

I changed file encoding of template.py

and also replaced  

        if isinstance(text, unicode):

            #~ text = text.encode("latin1","ignore")

            text = text.encode('utf8')

and explicitly changed all set_font to:

            #~ pdf.set_font(font,style,size)

            pdf.add_font('DejaVu', '', 'DejaVuSansCondensed.ttf', uni=True)

            pdf.set_font('DejaVu','',size)

but then I get:

Traceback (most recent call last):

  File "unicode_template.py", line 321, in <module>

    f.render("./invoice.pdf")

  File "unicode_template.py", line 135, in render

    self.handlers[element['type'].upper()](pdf, **element)

  File "unicode_template.py", line 172, in text

    pdf.cell(w=x2-x1,h=y2-y1,txt=text,border=0,ln=0,align=align)

  File "/home/nijole/Downloads/pyfpdf/fpdf/fpdf.py", line 632, in cell

    txt = self.normalize_text(txt)

  File "/home/nijole/Downloads/pyfpdf/fpdf/fpdf.py", line 1043, in normalize_text

    txt = txt.decode('utf8')

  File "/usr/lib/python2.7/encodings/utf_8.py", line 16, in decode

    return codecs.utf_8_decode(input, errors, True)

UnicodeDecodeError: 'utf8' codec can't decode byte 0xba in position 1: invalid start byte

Please, can you attach a minimal script to reproduce this?

You should pass unicodes when using utf8, do not pass strings with
.encode('utf8')
(using utf8 fonts you can avoid the if isinstance(text, unicode):
block completely)

Yes unicode python support is hard to master, luckily in py3k it is a bit easier

I used template.py invoice example, 

but in invoice.csv I tried to change all 'Arial' --> 'DejaVu'

f.parse_csv(infile="_invoice.csv", delimiter=";", decimal_sep=",")

f.pdf.add_font('DejaVu', '', 'DejaVuSansCondensed.ttf', uni=True)

f.pdf.add_font('DejaVu', 'B', 'DejaVuSans-Bold.ttf', uni=True)

and the problem was caused by '\xba'

'document_number';'T';115.30;27.80;125.30;33.30;'DejaVu';14.00;1;0;0;0;0;'I';'N\xba: ';2

***

another issue is in class Template 

    def __setitem__(self, name, value):

        ...

            if isinstance(value,unicode):

                value = value.encode("latin1","ignore")   

so   u"Sample ĄČĘĖŠŲ product"   will show only    "Sample  product ' 

but  "Sample ĄČĘĖŠŲ product"   will show   "Sample ĄČĘĖŠŲ  product '  ... :)

***

ps.: in template.py there was also 

            if font == 'arial black':

                font = 'arial'

which could be generalized (for DejaVu or other) 

        if font.lower().endswith(" black"):

            font=font[:-len(" black")].strip()
