Emacs: how to venvert documents to UTF-8 codepage

[Alain Muls]

Hi

I use emacs for formatting latex code. I use the utf-8 encoding for documents 
so that accented characters are correctly handled. When I get documents for 
my colleague (a notorious windoze user), the accented characters are replaced 
by somting like \370 which can not be displayed by emacs and which is not 
correctly compiled by latex.

How can I convert the docuemnts to utf-8 encoding. There is probably a command 
line utility that can do this, but I have no idea.

Tx/Alain
