Your correction would seem to be correct, looking at just the names
for the characters:  \CYRYI  rather than \CYRII.

But is this the way that those macro names have actually been used
previously in LaTeX ?
That is, maybe the mistake is deeper than what is in this file ?

LaTeX usage seems to be controlled by  inputenc.sty  where relevant
coding is:

Also relevant are files in  .../texmf/tex/latex/cyrillic

viz.
[GlenMorangie:tex/latex/cyrillic] rossmoor% grep CYRYI *.def
cp1251.def:\DeclareInputText{175}{\CYRYI}
cp855.def:\DeclareInputText{141}{\CYRYI}
cp866.def:\DeclareInputText{244}{\CYRYI}
cp866nav.def:\DeclareInputText{248}{\CYRYI}
iso88595.def:\DeclareInputText{167}{\CYRYI}
isoir111.def:\DeclareInputText{183}{\CYRYI}
koi8-ru.def:\DeclareInputText{183}{\CYRYI}
koi8-u.def:\DeclareInputText{183}{\CYRYI}
lcyenc.def:\DeclareTextSymbol{\CYRYI}{LCY}{248}
maccyr.def:\DeclareInputText{186}{\CYRYI}
macukr.def:\DeclareInputText{186}{\CYRYI}
t2aenc.def:\DeclareTextSymbol{\CYRYI}{T2A}{136}
x2enc.def:\DeclareTextSymbol{\CYRYI}{X2}{136}


That gives at least 9 different encoding positions in non-Unicode
fonts. Are they all accessing a glyph for
  a.  the same character ?
  b.  the *correct* character;  i.e.  Ux0407  ?
or
  c.  the incorrectly named character;  Ux0406 ?


Would  Evgenie Medvedev  or  A. Shipunov , or anyone else who has
had lots of experience with these encodings, please comment on this,
so that a possible error is not propagated any further; nor any new
error created by acting in haste.


Hope this helps,
