 \section{\class{wxFontMapper}}\label{wxfontmapper}
 
-TODO.
+wxFontMapper manages user-definable correspondence between logical font
+names and the fonts present on the machine.
+
+The default implementations of all functions will ask the user if they are
+not capable of finding the answer themselves and store the answer in a
+config file (configurable via SetConfigXXX functions). This behaviour may
+be disabled by giving the value of false to "interactive" parameter.
+
+However, the functions will always consult the config file to allow the
+user-defined values override the default logic and there is no way to
+disable this - which shouldn't be ever needed because if "interactive" was
+never true, the config file is never created anyhow.
+
+In case everything else fails (i.e. there is no record in config file
+and "interactive" is false or user denied to choose any replacement), 
+the class queries \helpref{wxEncodingConverter}{wxencodingconverter} 
+for "equivalent" encodings (e.g. iso8859-2 and cp1250) and tries them.
+
+\wxheading{Using wxFontMapper in conjunction with wxMBConv classes}
+
+If you need to display text in encoding which is not available at
+host system (see \helpref{IsEncodingAvailable}{wxfontmapperisencodingavailable}),
+you may use these two classes to find font in some similar encoding
+(see \helpref{GetAltForEncoding}{wxfontmappergetaltforencoding})
+and convert the text to this encoding 
+(\helpref{wxMBConv classes}{mbconvclasses}).
+
+Following code snippet demonstrates it:
+
+\begin{verbatim}
+if (!wxFontMapper::Get()->IsEncodingAvailable(enc, facename))
+{
+   wxFontEncoding alternative;
+   if (wxFontMapper::Get()->GetAltForEncoding(enc, &alternative,
+                                              facename, false))
+   {
+       wxCSConv convFrom(wxFontMapper::Get()->GetEncodingName(enc));
+       wxCSConv convTo(wxFontMapper::Get()->GetEncodingName(alternative));
+       text = wxString(text.mb_str(convFrom), convTo);
+   }
+   else
+       ...failure (or we may try iso8859-1/7bit ASCII)...
+}
+...display text...

+\membersection{wxFontMapper::wxFontMapper}\label{wxfontmapperwxfontmapper}
+
+\func{}{wxFontMapper}{\void}
+
+Default ctor.
+
+\wxheading{Note}
+
+The preferred way of creating a wxFontMapper instance is to call 
+\helpref{wxFontMapper::Get}{wxfontmapperget}.
+
+
+\membersection{wxFontMapper::\destruct{wxFontMapper}}\label{wxfontmapperdtor}
+
+\func{}{\destruct{wxFontMapper}}{\void}
+
+Virtual dtor for a base class.
+
+
+\membersection{wxFontMapper::CharsetToEncoding}\label{wxfontmappercharsettoencoding}
+
+\func{wxFontEncoding}{CharsetToEncoding}{\param{const wxString\& }{charset}, \param{bool }{interactive = true}}
+
+Returns the encoding for the given charset (in the form of RFC 2046) or
+\texttt{wxFONTENCODING\_SYSTEM} if couldn't decode it.
+
+Be careful when using this function with \arg{interactive} set to \true
+(default value) as the function then may show a dialog box to the user which
+may lead to unexpected reentrancies and may also take a significantly longer
+time than a simple function call. For these reasons, it is almost always a bad
+idea to call this function from the event handlers for repeatedly generated
+events such as \texttt{EVT\_PAINT}.
+
+
+\membersection{wxFontMapper::Get}\label{wxfontmapperget}
+
+\func{static wxFontMapper *}{Get}{\void}
+
+Get the current font mapper object. If there is no current object, creates
+one.
+
+\wxheading{See also}
+
+\helpref{wxFontMapper::Set}{wxfontmapperset}
+
+
+\membersection{wxFontMapper::GetAllEncodingNames}\label{wxfontmappergetallencodingnames}
+
+\func{static const wxChar**}{GetAllEncodingNames}{\param{wxFontEncoding }{encoding}}
+
+Returns the array of all possible names for the given encoding. The array is
+\NULL-terminated. IF it isn't empty, the first name in it is the canonical
+encoding name, i.e. the same string as returned by 
+\helpref{GetEncodingName()}{wxfontmappergetencodingname}.
+
+
+\membersection{wxFontMapper::GetAltForEncoding}\label{wxfontmappergetaltforencoding}
+
+\func{bool}{GetAltForEncoding}{\param{wxFontEncoding }{encoding}, \param{wxNativeEncodingInfo* }{info}, \param{const wxString\& }{facename = wxEmptyString}, \param{bool }{interactive = true}}
+
+\func{bool}{GetAltForEncoding}{\param{wxFontEncoding }{encoding}, \param{wxFontEncoding* }{alt\_encoding}, \param{const wxString\& }{facename = wxEmptyString}, \param{bool }{interactive = true}}
+
+Find an alternative for the given encoding (which is supposed to not be
+available on this system). If successful, return true and fill info
+structure with the parameters required to create the font, otherwise
+return false.
+
+The first form is for wxWidgets' internal use while the second one
+is better suitable for general use -- it returns wxFontEncoding which
+can consequently be passed to wxFont constructor.
+
+
+\membersection{wxFontMapper::GetEncoding}\label{wxfontmappergetencoding}
+
+\func{static wxFontEncoding}{GetEncoding}{\param{size\_t }{n}}
+
+Returns the {\it n}-th supported encoding. Together with 
+\helpref{GetSupportedEncodingsCount()}{wxfontmappergetsupportedencodingscount} 
+this method may be used to get all supported encodings.
+
+
+\membersection{wxFontMapper::GetEncodingDescription}\label{wxfontmappergetencodingdescription}
+
+\func{static wxString}{GetEncodingDescription}{\param{wxFontEncoding }{encoding}}
+
+Return user-readable string describing the given encoding.
+
+
+\membersection{wxFontMapper::GetEncodingFromName}\label{wxfontmappergetencodingfromname}
+
+\func{static wxFontEncoding}{GetEncodingFromName}{\param{const wxString\& }{encoding}}
+
+Return the encoding corresponding to the given internal name. This function is
+the inverse of \helpref{GetEncodingName}{wxfontmappergetencodingname} and is
+intentionally less general than 
+\helpref{CharsetToEncoding}{wxfontmappercharsettoencoding}, i.e. it doesn't
+try to make any guesses nor ever asks the user. It is meant just as a way of
+restoring objects previously serialized using 
+\helpref{GetEncodingName}{wxfontmappergetencodingname}.
+
+
+\membersection{wxFontMapper::GetEncodingName}\label{wxfontmappergetencodingname}
+
+\func{static wxString}{GetEncodingName}{\param{wxFontEncoding }{encoding}}
+
+Return internal string identifier for the encoding (see also 
+\helpref{GetEncodingDescription()}{wxfontmappergetencodingdescription})
+
+\wxheading{See also}
+
+\helpref{GetEncodingFromName}{wxfontmappergetencodingfromname}
+
+
+\membersection{wxFontMapper::GetSupportedEncodingsCount}\label{wxfontmappergetsupportedencodingscount}
+
+\func{static size\_t}{GetSupportedEncodingsCount}{\void}
+
+Returns the number of the font encodings supported by this class. Together with 
+\helpref{GetEncoding}{wxfontmappergetencoding} this method may be used to get
+all supported encodings.
+
+
+\membersection{wxFontMapper::IsEncodingAvailable}\label{wxfontmapperisencodingavailable}
+
+\func{bool}{IsEncodingAvailable}{\param{wxFontEncoding }{encoding}, \param{const wxString\& }{facename = wxEmptyString}}
+
+Check whether given encoding is available in given face or not.
+If no facename is given, find {\it any} font in this encoding.
+
+
+\membersection{wxFontMapper::SetDialogParent}\label{wxfontmappersetdialogparent}
+
+\func{void}{SetDialogParent}{\param{wxWindow* }{parent}}
+
+The parent window for modal dialogs.
+
+
+\membersection{wxFontMapper::SetDialogTitle}\label{wxfontmappersetdialogtitle}
+
+\func{void}{SetDialogTitle}{\param{const wxString\& }{title}}
+
+The title for the dialogs (note that default is quite reasonable).
+
+
+\membersection{wxFontMapper::Set}\label{wxfontmapperset}
+
+\func{static wxFontMapper *}{Set}{\param{wxFontMapper *}{mapper}}
+
+Set the current font mapper object and return previous one (may be NULL).
+This method is only useful if you want to plug-in an alternative font mapper
+into wxWidgets.
+
+\wxheading{See also}
+
+\helpref{wxFontMapper::Get}{wxfontmapperget}
+
+
+\membersection{wxFontMapper::SetConfig}\label{wxfontmappersetconfig}
+
+\func{void}{SetConfig}{\param{wxConfigBase* }{config}}
+
+Set the config object to use (may be NULL to use default).
+
+By default, the global one (from wxConfigBase::Get() will be used) 
+and the default root path for the config settings is the string returned by
+GetDefaultConfigPath().
+
+
+\membersection{wxFontMapper::SetConfigPath}\label{wxfontmappersetconfigpath}
+
+\func{void}{SetConfigPath}{\param{const wxString\& }{prefix}}
+
+Set the root config path to use (should be an absolute path).
