[tex-k] makeindex breaks up index group on a capitalized entry

[geolsoft at mail.ru]

Thanks to the top-grade comments by Thomas Esser and Olaf
Weber, my problem (see thread "[tex-k] \write writes out
TeX's `^^' quartets instead of 8-bit chars") is fully
resolved now.

Now I have another problem, but I am not sure this is the
right place to post it to.  If it actually is not, could
someone please kindly recommend me an appropriate mailing
list?

I now post this message to tex-k at tug.org,
tex-eplain at tug.org, and texhax at tug.org (people who are
subscribed to few of these, please don't be too hard on
me---I don't know where to seek help).

I've already tried posting to CyrTeX-ru mailing list which
deals with Russian/Cyrillic TeXing, but nothing came out of
it (mailing list <CyrTeX-ru.vsu.ru>, message at
https://info.vsu.ru/Lists/CyrTeX-ru/Message/2199.html, but
it's all in Russian; below I give translation into English,
with more details.)



The problem I have is related to generating Cyrillic indices
with makeindex(1) by Pehong Chen, version 2.14 [02-Oct-2002]
(kpathsea + Thai support).

I use tetex-bin 2.0.2-10, Web2C 7.4.5 on Debian GNU/Linux
2004-04-02 Sid.

I use plain TeX format and I read in eplain macro package,
but it seems that my problem is local to makeindex.

I have these for my locale settings:

$ echo $LC_CTYPE; echo $LC_COLLATE
LC_COLLATE=ru_RU.KOI8-R
LC_CTYPE=ru_RU.KOI8-R


where ru_RU.KOI8-R is the locale for Russian with KOI8-R
encoding (my TeX sources and intermediate files are all in
this encoding).

The source file is:

--------------------start testidx.tex--------------------
\input eplain

\idx{Meksika}
\idx{martyshka}
\idx{motylyok}
\idx{moloko}
\idx{masshtab}
\idx{marazm}

\readindexfile{i}

\bye
--------------------end testidx.tex--------------------

(I have transliterated index entries into Latin, in the
actual testidx.tex they are all equivalent Cyrillic
characters from the extended ASCII.)

Now I run

$ tex -translate-file=cp8bit testidx
This is TeX, Version 3.14159 (Web2C 7.4.5)
 (/usr/share/texmf/web2c/cp8bit.tcx)
(./testidx.tex (/usr/share/texmf/tex/eplain/eplain.tex)
No index file testidx.ind. [1] )
(see the transcript file for additional information)
Output written on testidx.dvi (1 page, 200 bytes).
Transcript written on testidx.log.


and get testidx.idx:

--------------------start testidx.idx--------------------
\indexentry{Meksika}{1}
\indexentry{martyshka}{1}
\indexentry{motylyok}{1}
\indexentry{moloko}{1}
\indexentry{masshtab}{1}
\indexentry{marazm}{1}
--------------------end testidx.idx--------------------

(again, I transliterated Cyrillic chars into Latin).  So far
so good.  Now, when I run

$ makeindex -L testidx.idx
This is makeindex, version 2.14 [02-Oct-2002] (kpathsea +
Thai support).
Scanning input file testidx.idx....done (6 entries accepted,
0 rejected).
Sorting entries....done (17 comparisons).
Generating output file testidx.ind....done (16 lines
written, 0 warnings).
Output written in testidx.ind.
Transcript written in testidx.ilg.


I get the following in my testidx.ind:

--------------------start testidx.ind--------------------
\begin{theindex}

  \item marazm, 1
  \item martyshka, 1
  \item masshtab, 1

  \indexspace

  \item Meksika, 1

  \indexspace

  \item moloko, 1
  \item motylyok, 1

\end{theindex}
--------------------end testidx.ind--------------------

(again, I transliterated Cyrillic chars into Latin).  As you
can see, index entries are sorted correctly, even the
capitalized `Meksika' got into right place, but makeindex
broke up the group for letter `m' on the capitalized word.
makeindex does not do this for index entries in Latin chars.

What puzzled me the most is that makeindex sorted entries
correctly, knowing that Cyrillic `M' is a capitalized
Cyrillic `m', which indicates that makeindex applied my
locale settings (it does correct _sorting_ even on more
complex inputs, with entries starting on many different
letters), but still it _broke up the group for letter `m'_
on a capitalized word.

I must have skipped a step or two, or maybe I misunderstand
how makeindex works with locale settings?  Or maybe I need a
special style file for makeindex to stop breaking Cyrillic
index groups on capitalized entries?

Thanks in advance for any clues on this.
