How do I use entities in DocBook in ConTeXt

How do I use entities in DocBook in ConTeXt

[Guy Worthington]

Although I use emacs as a text editor, I'm not confident in using
utf-8 encodings.  So if I can I'd prefer to use entities for the
characters not defined in ASCII.

How can I define entities such as "“" (for the left double
quotation character) and "”" (for the right double quotation
character) so as the context-processor can process them.

see xtag-ent.tex

(Look mom -- I'm reading the source files.)



Thanks for the pointer Hans, 

I wound up defining "“" as:

   \defineXMLentity [ldquo] {``} 

and it seems to be doing what I want.

Docbook comes with a lot of entities defined, see the subdirectory ent
in the docbookx distribution.

Unfortunately, DocbookInContext does not yet recognize those
entities. I suppose I should make an effort to translate the entity
files to Context.

xtag-ent can only be used if it agrees with the entity definitions in
the DTD.

emacs 21 is really a good utf-8 editor. It has the TeX input method,
meaning that many characters can be input by giving their TeX name,
e.g. \sum. Loading utf-8 files is a bit clumsy, with the command `C-x
RET c' (universal-coding-system-argument).

If you put this at the end of the file, it is automatically read in
utf-8 encoding next time:

%% Local Variables:
%% current-language-environment: UTF-8
%% coding: utf-8
%% default-input-method: TeX
%% End:

And this is a better way to read it in utf-8 encoding
non-automatically (commands to be put in .emacs):

;; find a file (read-only) with utf-8 coding system
(defun find-file-utf-8 (file)
  "Find file FILE with utf-8 coding system."
  (interactive "FFile name: ")
  (let ((coding-system-for-read 'utf-8))
	(find-file file)))

(defun find-file-read-only-utf-8 (file)
  "Find file FILE read-only with utf-8 coding system."
  (interactive "FFile name read-only: ")
  (let ((coding-system-for-read 'utf-8))
	(find-file-read-only file)))

;; bind C-x C-f and C-x C-r to these functions
(global-set-key [(control ?x)(control ?f)]
				'find-file-utf-8)
(global-set-key [(control ?x)(control ?r)]
				'find-file-read-only-utf-8)

You're a great evangelist for utf-8.  However Hans and you have made
it easy to customize a TeX-stylesheet (if that's the right word for
the TeX file that wraps the XML file).  And consequently I'm not yet
ready to dump my faithful (and fast) NTEmacs for TEI-emacs, which has
all the bells and whistles you're talking about.

I guess that I'm just too comfortable in my 7-bit world.
