Hi,
I'm working on a Linux machine which has UTF-8 encoding. The docbook 5.1 I'm
working with is declared:
<?xml version="1.0" encoding="utf-8"?><!DOCTYPE book [<!ENTITY version "0.1
unreleased">]>
Entities changed a while back (relaxng changed things), but so far as I know I
should still be able to work with numeric entities when using odd characters
which are part of UTF-8. I'm trying to get some box drawing characters to work,
specifically because I need to illustrate a file directory structure which has
been output like this from the "tree -d" command. Here's a short sample:
> tree -d -L 2 /etc | tail -n 20 | tail -n 6│ ├── pluginconf.d│ ├──
> protected.d│ └── vars└── yum.repos.d
As you can see the vertical and horizontal box drawing characters are used.
When I redirect this to a file or copy and paste into the document all I get is
a substitute...each shows as "#". So I tried to use numeric entities instead.
As an example "boxh" (horizontal box line) should work as "─". This does
not work, and rendering still ends up as "#". I tried the numeric code for the
plus/minus character, "±", and this does work. I don't know if it proves
anything, but since my UTF-8 terminal shows all of the above characters just
fine on a terminal, it seems like the ability to output is not in
question...perhaps this is an invalid assumption.
Btw, one reference on the Unicode numeric value is from:
http://www.oasis-open.org/docbook/documentation/reference/html/iso-box.html
Under Docbook 5.1, what do I need to do to use this numeric entity other than
using UTF-8 and the numeric entity syntax? Is there an additional XML
declaration I need?
Thanks!
