I don't have any gambas or Visual Basic experience, but I have used Microsoft
tools
before (Visual FoxPro).

Any chance you could post the traceback in its entirety? We'd like to fail as
gracefully as possible when a given translation isn't yet available.

Good!

It is because by default reportlab (and dabo report designer) uses Type 1
Times,
Helvetica, and Courier fonts. These fonts don't have very many special
characters
defined at all, so they are only really useful as default fonts for American
English
countries.
You'll have to find a TrueType font or fonts that support the characters you
want to
print, put them in your app's resources/ directory, and tell reportlab about
them.
Add a 'registerFonts.py' script in your application's home directory, with
these
contents:
{{{
import os
from reportlab.pdfbase import pdfmetrics
from reportlab.pdfbase.ttfonts import TTFont
def registerFonts(homedir):
for fname in os.listdir(os.path.join(homedir, "resources")):
name, ext = os.path.splitext(fname)
if ext == ".ttf":
#print "registering %s..." % name
pdfmetrics.registerFont(TTFont(name, os.path.join(homedir, "resources",
fname)))
}}}
And somewhere in the initialization of your application (main.py file or dApp
subclass, for instance) make the call:
{{{
from registerFonts import registerFonts
registerFonts(app.HomeDirectory)
}}}
And now, in your reports, modify Reports.Defaults.FontName to be the name of
the true
type font you want your objects to use by default. Or, modify each string
object
individually.

I don't know which freely-available truetype fonts support arabic (I use the
DejaVu
fonts) and I also don't know how to tell you to deal with right-to-left
presentation
of the characters. But I hope this at least gets you started.
