[Zope] Unicode Error ASCII -> decoding error: ordinal not in range(128)

[Shashank Ashtikar]

Hello friends,

I am trying to import unicode content in to ZODB using an external method.
This content is being added as a property.

The error that I am Getting is

Error Type: UnicodeError
Error Value: ASCII decoding error: ordinal not in range(128)

I did some googling and I found out that this is because of pythons
default encoding being ascii. But I did not come across any particular 
solution. The text that I am trying to import is Hindi language text 
(i.e. ISO - 10646 encoding.) 

The actual traceback of the error is,
Traceback (innermost last):
  Module ZPublisher.Publish, line 98, in publish
  Module ZPublisher.mapply, line 88, in mapply
  Module ZPublisher.Publish, line 39, in call_object
  Module Products.ExternalMethod.ExternalMethod, line 224, in __call__
   - __traceback_info__: ((<TransparentFolder instance at 8cf1f68>, <HTTPRequest, URL=http://gnu.hbcse.tifr.res.in:9673/IndicTrans/indic2/Programs/import_po>), {}, (None,))
  Module /usr/lib/zope/lib/python/Products/GNOWSYS/Extensions/po_import.py, line 47, in manage_addPoFile
  Module OFS.PropertyManager, line 247, in manage_addProperty
  Module ZPublisher.Converters, line 123, in __call__
UnicodeError: ASCII decoding error: ordinal not in range(128)

The line 47 in the external method is

objRef.manage_addProperty('trString', msgText1, 'utext')

here "objRef" is the object handle which I got using restrictedTraverse API
"trString" is the property id and "msgText1" is the variable containing
actual unicode string.

Any help or pointers???

Thanks in Advance.
