Tvheadend

Hi
I found one big problem. Example i have a channel:
Kuchnia+ HD
MiniMini+ HD
Planete+ HD

In TVHeadend automatic create shortcut to icon:
path/Kuchnia+_HD.png
path/MiniMini+_HD.png
path/Planete+_HD.png

And when i put to path this files png name as i show, that in TVHclient and XBMC not show icon for this channel.
I must change name in path to:
path/Kuchnia_HD.png
path/MiniMini_HD.png
path/Planete_HD.png

and names files also:
Kuchnia_HD.png
MiniMini_HD.png
Planete_HD.png

and now icon is show ok. Problem is when in name is name then character "+" and then "_" and "HD".
