Tour editor generates strange chars before hotspots

Hi Klaus,

after generating some tours I was annoyed of the formatting of the generated hotspots,
because they look like this after generation:

<!-- place your scene hotspots here -->
		<hotspot name="spot1" style="skin_hotspotstyle" ath="-59.567" atv="19.139" linkedscene="scene_haus_1_anbau" />
		<hotspot name="spot2" style="skin_hotspotstyle" ath="-91.396" atv="13.955" linkedscene="scene_haus_1_garten" />

Much more usable and clearer is a fomat like this:

<!-- place your scene hotspots here -->
    	<hotspot name="spot1" 
    		style="skin_hotspotstyle" 
    		ath="-59.567" 
    		atv="19.139" 
    		linkedscene="scene_haus_1_anbau" />
    	<hotspot name="spot2" 
    		style="skin_hotspotstyle" 
    		ath="-91.396" 
    		atv="13.955" 
    		linkedscene="scene_haus_1_garten" />

To edit this manually is a lot of needless work.

OK, I'm working with my favourite tool BBEdit and a search-and-replace shoukd be one of my
easiest practices. That was my first thought ...

I copied the part between the hotspots to replace it with /r/t (new line and then one tab)
but - NO occurrence is found. Huh?

I looked at the invisible chars and see flipped question marks. Here is a screenshot:

Between the hotspots is this obscure flipped question mark with two tabs followed.

Where is that generated and where can I setup another formatting of the generated hotspots?
I don't want to have more work than needed

Thanks a lot in advance and regards,

Josch
