[trunk] Euro-sign and other 'strange chars' not displayed correctly

[EdbO]

Used software: trunk of 29-01-2009 @ 22:00 (CentOS 5.2 with python 2.4)

'Strange chars' like ä á à ß Ô Ú Â and so on are not printed correctly. I got e.g. a € for the € sign. Trying to use another encoding doesn't work.

Maybe there is already a bug reported for this, but I can't find it.

We decided to create a addons-extra to manage unicode fonts using dejavu.
Wait for this module.

Why is it working with RC3 on Fedora 10?

[EdbO (edbo-design-deactivatedaccount)]

Why creating a new module? The solution is so simple! I found the solution on the forum, suggested by Intersol ( http://openerp.com/forum/post15847.html#15847 ) .

#--- intersol DejaVu fornt patch for enabling UTF-8 support in normal reports
import reportlab.rl_config
reportlab.rl_config.warnOnMissingFontGlyphs = 0

from reportlab.pdfbase.ttfonts import TTFont
from reportlab.pdfbase import pdfmetrics

pdfmetrics.registerFont(TTFont('Times-Roman','DejaVuSerif.ttf'))
pdfmetrics.registerFont(TTFont('Times-BoldItalic','DejaVuSerifBoldItalic.ttf'))
pdfmetrics.registerFont(TTFont('Times-Bold','DejaVuSerifBold.ttf'))
pdfmetrics.registerFont(TTFont('Times-Italic','DejaVuSerifItalic.ttf'))

#pdfmetrics.registerFont(TTFont('Helvetica','DejaVuSans.ttf'))
# disabled: this one does give an error, should be investigated
pdfmetrics.registerFont(TTFont('Helvetica-BoldItalic','DejaVuSansBoldOblique.ttf'))
pdfmetrics.registerFont(TTFont('Helvetica-Bold','DejaVuSansBold.ttf'))
pdfmetrics.registerFont(TTFont('Helvetica-Italic','DejaVuSansOblique.ttf'))

pdfmetrics.registerFont(TTFont('Courier','DejaVuMonoSans.ttf'))
pdfmetrics.registerFont(TTFont('Courier-Bold','DejaVuMonoSansBold.ttf'))
#--- end of patch

I've added the above in bin/report/render/rml2pdf/trml2pdf.py starting at line 57 just below the import-section. Instead of the Dejavu-fonts I'm using the Arial-fonts, which I added to /usr/lib/python2.4/site-packages/reportlab/fonts

Got my Euro-sign back and the 'strange chars'.

Maybe there is a possibility to make a config-option for the fonttypes.

[EdbO (edbo-design-deactivatedaccount)]

I've added a sample-pdf.

You have to change the 'Helvetica'-font on the reports to a different font. In my case I've also added
pdfmetrics.registerFont(TTFont('Arial','arial.ttf')) to the file. ReportLab uses 'Helvetica' as it's standard font, so it cannot be changed.

On my reports I changed every para-style with the Helvetica-font with the defined Arial-font.

The result is the attached PDF.

Because:
1. v5 is frozen, we can not add new feature now. Putting it as a module will allow to publish it in february.
2. DejaVU fonts are heavy (several Mbs), I don't want to include them in each report (or sever code) for those that do not need them. So, only companies that need to use unicode report will use it.
3. I am not sure this solution is the best, and we have no time to check this. V5 is the priority.

[Fabien (Open ERP) (fp-tinyerp)]

Can you create a blueprint, so that we don't forget to planify this for
after v5 ?
Thanks,

Considering the Eastern Aisan language support, the solution of using Dejavu font as the replacement font is not a once and for all solution. Do we have have better ideas?
