thanks for the pointer.

yes. 8-bit cyrillic font encodings are more "clean" WRT hyphenation
and kerning, and do not need "false" ligatures.

more portable way is to use \textcompwordmark instead of \cydot
(recent official version of ot2enc.def does not define \cydot command
anymore). one can \let\cwm\textcompwordmark and use \cwm instead of
\textcompwordmark if she finds the latter a bit long to type.

 LS> 1) Is there a version of the "WN" without the poisonous

i just created such virtual fonts which refer to WN fonts but do not
have "false" ligatures, and sent them to you in a separate letter. Are
these WL fonts important enough to have them officially supported?

 LS> 2) Which came first, the LH series with MS-DOS cp866 encoding or

i'm not sure but it seems that probably LH LCY-encoded fonts were the
first (WVCY fonts are dated 1995, but LH fonts were available at
1992--1993).

 LS> 3) Are WNCY and WN fonts metrically idantical where they both
 LS> exist?

i htink that no. there are a lot of small differences in design of
glyphs between AMS WNCY fonts and LH fonts, and thus differences in
metrics.

 LS> 4) The WNCY and the BaKoMa CMCY series: are these still the only
 LS> CM compatible cyrillic fonts in Type 1 format?

it seems that yes.
