So here are solution, new zope tag :o). Simply place __init__.py file listed 
below into some new subfolder in lib/python/Products folder and place 

<dtml-nationaxmlizer>
	nationalized text here with ěščřžýáíéďťňóúůöëäü
</dtml-nationaxmlizer>

text between these new tags in your page. Enjoy!


__init__.py:

from string import split, strip, join, find
import locale
import DocumentTemplate.DT_Util
from DocumentTemplate.DT_String import String

class NationaXMLizer:
    """
    Function:
        * Remove redundant whitespaces
            based on 'unitws' tag from Toby Dickenson 
<tdickenson at geminidataloggers.com>
        * Replace characters >128 with &#xx; entities in respect with defined 
codepage (cp1250), see znak.decode('yourcodepage') and define your own

        Simply place this file named as __init__.py into some new subfolder in 
lib/python/Products folder and place

        <dtml-nationaxmlizer>
            nationalized text here with national characters
        </dtml-nationaxmlizer>
