[OpenLayers-Users] WFS layers loaded are not visible

[Arnd Wippermann]

Hi Alessio,

What browser do you work with? I have had the problem with IE. In Firefox
the WFS from UMN MapServer and also an own KML would be loaded and could be
seen, but not in IE6. The layer would be displayed in the layerswitcher,
that was all. From Firebug I grabbed the request and put it in IE6. There I
get the message, that the xml had wrong characters. I solved the problem,
that I set in my proxy-script

Response.ContentType = "text/xml"
Response.CharSet = "iso-8859-1"

It helped, because both WFS and my own build KML came with "iso-8859-1". I
use also OL 2.5.

Mit freundlichen Grüssen
