Do I need to convert them to utf8 or unicode before

Do I need Python-2 to implement non US-ASCII site (and not latin-1)?

My templates are just fiels with %(var)s -style things inside.
And thank you mentioning XSLT with referring to
working site - I will see if this fit in my case.

Wow! If it works as advertized - this is what I need.

Can I also embed some python sentences there to handle
hard cases?

I did it already.

Demos are sometimes more valuable than tutorials.
In fact, I feel a need to reread overviews on XML (XSLT, XPath, AFs etc)
to have better idea what they do before looking at
demos.
