Hi, i am newbie on this forum and i hope that i am in the right place

I have an old palm m125 and i use plucker on windows to convert some html files or entire sites to read on my palm device but in some cases, plucker does not recognize well the source text and i view on my reader strange characters such as letters with accents and others.
For example: i have tried to convert the installation manual for debian from debian site:
http://www.debian.org/releases/stabl.../index.html.en
but when i read this document on my palm, i do not read well it!!!
Why?
I have tried to change character encoding, but never i resolve!
Please help me!
