By default, xfNetLink .NET uses the ISO-8859-1 character set to encode/decode characters when sending data from .NET to Synergy.

This works fine for most customers, but ISO-8859-1 does not define characters for values in the range 128-159. If you need characters in this range, such as the Euro symbol (€) at 128, you can change the encoding used by xfNetLink .NET to Windows-1252 in the application configuration file (aka, config file). You must do this manually, as the encoding option is not available in the xfNetLink .NET Configuration utility.

(If you are not using a config file, you can use the XFNLNET_CLASS_ENCODING setting to specify the default character set.)

To change encoding, use a text editor to add the bolded line to your config file:

<?xml version="1.0" encoding="utf-8"?>

<configuration>

 <configSections>

   <sectionGroup name="xfnlnet">

     <section name="default" type="System.Configuration.NameValueSectionHandler, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />

   </sectionGroup>

 </configSections>

 <startup>

   <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.7.2" />

 </startup>

 <xfnlnet>

   <default>

     <add key="encoding" value="Windows-1252" />

   </default>

 </xfnlnet>

</configuration>

Any of the encodings listed in the "List of encodings" table in https://docs.microsoft.com/en-us/dotnet/api/system.text.encoding are valid. Just put the encoding name in quotes as shown above.
