I forgot to mention a major point: compatibility.

When a ZPT is internally stored a unicode string then content returned by 
methods called through the ZPT will be implicitly  converted to unicode.
This will definitely raise UnicodeDecodeErrors. So how to deal with this 
issue?

 - allowing only unicode textual content when calling macros, PyScript etc.

 - converting non-unicode to unicode inside the TAL code using some
   encoding. The encoding could be specified as property of the called
   method (function properties) or object.

We really _need_ to discuss this issue early to minimize side effects
and to be able to provide the best compatibility possible.
