[xml/sgml-pkgs] Bug#796871: dbtoepub: Incorrect index ordering for Norwegian ( Bokmål and Nynorsk)

[Petter Reinholdtsen]

Package: dbtoepub
Version: 0+svn9150-2

The index ordering for the language codes nb and nn are incorrect when
building a book using dbtoepub.  The example docbook file should produce
an index ordering like this:

  A
  Alle inne, test

  B
  Bare tull, test

  Æ
  Ærlig talt, test

  Ø
  Øvrigheten, test

  Å
  Åndalsnes, test

Instead it is producing this ordering for nb, nn and no:

  Symboler
  Ærlig talt, test

  A
  Alle inne, test
  Åndalsnes, test

  B
  Bare tull, test

  O
  Øvrigheten, test

There are three errors here.  First of all, Æ is not a symbol, it is a
letter ordered between Ø and Å.  Second, Å and Ø is not variations of A
and O, but separate letters in the Norwegian languages, ordered ÆØÅ
after Z in the Norwegian alphabet.

This is the test document I am using:

<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook V4.5//EN"
"http://www.oasis-open.org/docbook/xml/4.5/docbookx.dtd">
<book lang="nb">
  <bookinfo>
    <title>Example demonstrating wrong nb indexterm sorting</title>
  </bookinfo>
<preface>
<title>test</title>
<indexterm><primary>Alle inne</primary></indexterm>
<para>test "polarity"</para>
<indexterm><primary>Ærlig talt</primary></indexterm>
<indexterm><primary>Øvrigheten</primary></indexterm>
<indexterm><primary>Åndalsnes</primary></indexterm>
<para>text is good</para>
<indexterm><primary>Bare tull</primary></indexterm>
<para>text is great</para>
</preface>
<index></index>
</book>
