-For larger projects I recommend storing everything but .hhp file into one .zip archive. (The contents file
-would then be referred to as myhelp.zip\#zip:contents.hhc)
+{\bf Localization note:} In addition, .hhp file may contain line
+
+\begin{verbatim}
+Charset=<rfc_charset>
+\end{verbatim}
+
+which specifies what charset (e.g. "iso8859\_1") was used in contents
+and index files. Please note that this line is incompatible with
+MS HTML Help Workshop and it would either silently remove it or complain
+with some error. See also
