Issue with encoding of marker and label texts in OpenLayers Maps

[Buss_Simon1 (Buß Simon)]

Hi,
i am using FNC Maps and if i include (German) special characters the encoding is broken.

var lMarkerTitle := '123 - Beispielprojekt ÄÖÜß';
TMSFNCOpenLayers1.AddMarker(lLat, lLong, lMarkerTitle, lMarkerIconData);

How do I fix this?
