Hi All,

I'm suffering with two different types of UnicodeDecodeError with a Zope 
2.12 project...

The first type of problem occurs when a form is submitted and the form 
fields contain encoded strings. Somewhere down the line I get:

   Module zope.i18n, line 166, in interpolate
   Module zope.i18n, line 161, in replace
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 5: 
ordinal not in range(128)

So, my question is how do I get strings submitted to the publisher 
(ideally) end up as unicode objects not encoded strings? Failing that, 
how do I find out what encoding the browser has provided?

The second type of problem only occurs in IE and Safari, where viewing a 
page that contains some non-ascii-able data:

   Module ZPublisher.Publish, line 127, in publish
   Module ZPublisher.mapply, line 77, in mapply
   Module ZPublisher.Publish, line 47, in call_object
   Module Products.Five.browser.metaconfigure, line 427, in __call__
   Module Products.Five.browser.pagetemplatefile, line 126, in __call__
   Module Products.Five.browser.pagetemplatefile, line 60, in __call__
   Module zope.pagetemplate.pagetemplate, line 116, in pt_render
    - Warning: Macro expansion failed
    - Warning: <class 'zope.tal.taldefs.METALError'>: macro nesting 
limit (100) exceeded by u'root/standard_template.pt/macros/nav'
   Module StringIO, line 270, in getvalue
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 10: 
ordinal not in range(128)

Two things are weird here:

- Why am I getting a macro nesting limit? This seems to be a recurring 
problem (excuse the pun) with Zope 2.12 page templates where if there's 
an error in a standard template, I get this error when a template that 
uses it is rendered.

- Why am I getting this decoding error only with these browsers? Firefox 
and Chrome work just fine... Is the publisher doing something special 
with a header these browsers send that IE and Safari are not? If so, how 
do I make it do the "right thing" for IE and Safari?
