[GoogleCodeExporter]

STEPS TO REPRODUCE:
I've a code like this
onCreate()
{
iap_helper = new IabHelper(this, app_key);
iap_helper.enableDebugLogging(true);
iap_helper.startSetup(this);
}

onIabSetupFinished(IabResult result)
{
iap_helper.queryInventoryAsync(this);
}

EXPECTED OUTPUT:
SkuDetails should have valid price field like "price":"1,10 €",

ACTUAL OUTPUT:
instead it has malformed price field like "price":"1,10┬áÔé¼",

Note: It returns malformed currency sign for all of my apps (tested two, one 
published long time ago, another unpublished and under testing).

@Olli (#1),   this doesn't occur on my live app. at all. 
check your skudetails class (did you change it?).  
Perhaps you are still using v2 market billing?
