[tex-live] Problem with 'mathtext' package after update of 'cyrillic' one

[Vladimir Lomov]

Hello,
today update of TeX Live 2018 (pretest) breaks in another way the same
document as 'latex' package earlier. The problem is with 'mathtext'
package from t2 bundle (https://ctan.org/pkg/t2).

I attached minimal example document to show the problem. This is
relevant part of .log file:

------------------------------ 8< --------------------------------
! Package inputenc Error: Unicode character П (U+41F)
(inputenc)                not set up for use with LaTeX.

See the inputenc package documentation for explanation.
Type  H <return>  for immediate help.
 ...                                              
                                                  
l.15 П
       роба пера.
------------------------------ 8< --------------------------------


P.S. As for my previous report I decided to fix the '[]' portion of
'\ProvidesPackage' because that was much easier.
