Document in Esperanto with Docbook

[Markos <markos@c2o.pro.br>]

Hi,

I use Docbook to write documents in Portuguese and English.

I would like to start using Esperanto with Docbook.

How to write the letters of Esperanto with diacritic marks, ĉ, ĝ, ĥ, ĵ, 
ŝ, and ŭ?

Any tip?

Thanks,
Markos

PS- I use Debian 6.0 (Squeeze) with the script "jw" to generate the html 
files from xml sources.
