Hi,

I have problem specifying font encoding: it works only until font switching
>command. I write (the example from Willi Egger):

>   \enableencoding[ec]
>   \enableregime[windows]

You only have to \enable encoding if there is a real reason for it. 
Normally the encoding is switched with the font. So, it looks like a 
misconfiguration.

You can add the following code to cont-new.tex (assuming you use pdfetex)

\unprotect

\def\tracedfontencoding#1%
   {\ifcsname\??ff#1\s!encoding\endcsname
      \space[\csname\??ff#1\s!encoding\endcsname]%
    \fi}

\def\tracedfontname#1%
   {\ifcsname\??ff\fontclass#1\endcsname
      #1\tracedfontencoding{\fontclass#1}\space->\space
        \@EA\tracedfontname\csname\??ff\fontclass#1\endcsname
    \else\ifcsname\??ff#1\endcsname
      #1\tracedfontencoding{#1}\space->\space
        \@EA\tracedfontname\csname\??ff#1\endcsname
    \else
      #1%
    \fi\fi}

\protect

You can now say something like

\message{\tracedfontname{Serif}} and see what font name is actually used 
and where in the chain the encoding is set.

The last name in the row should be defined in a map file and mapped onto a 
real filename. Either this map file is loaded runtime, or the entry should 
be in your local pdftex map file.

Now, if there is no [ec] in this chain, you're not using ec, which means 
some error in the setup.

Once you've sorted out what you want / need, we can add some entries to 
typescripts useful for your language
