Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
How are you getting characters, please? or where? I need to ask first.
Do they look like odd 'hieroglyphics' or little picture-symbols? if so, that's a peculiar sort of font, and I would have to know about the device these are appearing on, to advise you how to correct the problem.
That's OK. You can take up this case again whenever you wish.
