I can't play a message that contains <. From what I understood it is because it's considered as a XML tag. I could not find a way to escape it.
I tried to replace it by < and play that chars literally. Also tried SPEAKFLAGS SPF_IS_NOT_XML, then it speaks the text but ignores the <.
Is there any way to easily speak "lower than" when it finds <, as it does with >?
