I'm glad my instructions were of use to somebody and thanks for providing some additional tips. I kept track of what I was doing in Word so I don't know if copying and pasting from that is what has introduced the character errors.
I also tried to get the images to work. I could get them to load on other things such as bubbleupnp to send to other renderers (bubbleupnp actually dislikes endless streams so doesn't work with this) but the RuneUI wouldn't load them. I'm pretty sure the RuneUI doesn't support them as most radio streams don't typically have accessible artwork.
