maybe you can do this announce better, because you can explain the
importance of WLCY fonts to west people better than i. :)

that would be nice.

The same is valid for T2A. With T2A:
a) Russian and Ukranian users can conform to T2A
b) Russian users conform to CP1251
:-)

so there is really no need to create yet another incompatible and
unsupported encoding (with illegal name: encodings started with T are
reserved as standard LaTeX encoding; but T2 is not registered as such;
only T2A, T2B, T2C and yet-to-come T2D).

could you please elaborate?

no. if the encoding in Malyshev's fonts differs from standard T2A
encoding, then there will be unpredictable errors and mess-ups when
one will try to convert to vectorial PS/PDF output by substituting
TeX's internal standard T2A encoding with a different encoding used in
Malyshev's fonts.

this substitution may work reliably on some documents which happen to
use glyphs which are encoded identically in both T2A and in Malyshev's
fonts, but it will generally fail for anything more general.

so, distributing fonts which encoding differs from standard encoding
and claiming that they can serve as a replacement for standard
encoding is a misleading.

though, one needs to perform a check on current version of Malyshev's
fonts to find out how much the differences in their encoding are. if
there are any non-standard changes/replacements/additions WRT the
standard T2A in those fonts, then they definitely should not be used.

i think that metrics (do you mean kerning?) in his fonts are
compatible with shapes of cmcyr fonts, so that is okay provided that
cmcyr have good kerning.
