[mapserver-users] WMS call with layer names containing a space.

[Jeff McKenna]

I was just reading a recent discussion on this, might be the same 
discussion 
(http://osgeo-org.1560.x6.nabble.com/Allowing-spaces-in-layer-names-WMS-WFS-td5213960.html).

Bob can you file a little test case for this (tiny mapfile, commands to 
use to test), as a new ticket on the MapServer tracker? 
https://github.com/mapserver/mapserver/issues  I can't find an existing 
ticket, so we might as well record one.
