[docbook-apps] Ä - non SGML character number 132, only uppercase foreign char

[chlor]

Hi

I have problems with writing uppercase danish (and german) characters in
SGML files.

I get the error:
non SGML character number

I get the same error even if I write a comment with danish uppercase like:
<!-- ÅÄ€ -->

The same letter in in lowercase does not give an error
<!-- å -->
Special symbols does not give an error either
<!-- µ¿¡®©°¶¹²³»« -->

To work around the problem I tried to use the HTML entities &Aring; but
that gives wrong encoding in the html output.

Any hint much appreciated.

The version I am using:
$ docbook2html -v
DocBook-utils version 0.6.14 (jw version 1.1)

DocBook-XML is version 4.5

best regards
Hans Schou
