Yes, the reason is that makeinfo adds the `Local Variables' section
(with the `coding:' tag) before the Info tag table, and on file reading
Emacs looks for this sections only within 3000 characters from the end of
the file.

The file in question is the Emacs FAQ from Emacs CVS.  Its tag table
is not too huge, but still larger than the 3000 limit.

If there is no @documentencoding, makeinfo could look for the `coding:'
tag in the first lines or in the `Local Variables' section of the
source Texinfo file, and copy it to the Info output file.  For instance,
the Emacs FAQ source file faq.texi has the `coding:' tag, but no
@documentencoding, and makeinfo doesn't try to read it.

However, this is a minor problem because it is easy to add
@documentencoding to the source Texinfo file.  The main problem is that
given the @documentencoding in the source file, makeinfo writes the
`coding:' tag before the tag table in the Info output file, and Emacs
can't find it.
