TextBlock TextFormatting ArgumentOutOfRangeException

When displaying some strings in TextBlock I am getting the exception below. I will update here once I find the problematic string.

Exception Info: System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.

Thanks for investigating the causing string. Will have a look shortly. My guess is that I somehow don’t handle non breaking text that needs to wrap properly.

Haven’t had any reports of such issue. So I close it for now.
