Been using the "replace" method. I've tried to simply find it in the string, as well as searching for it as a regular expression and just can't seem to get rid of it!
Ah! Figured it out. Thank you very much Anglewatt for asking about the encoding because that made me think of how I saw "\u00dcT:" in the returned unaltered JSON stream instead of "ÜT:". I had figured that the encoding was probably to blame but for some reason didn't think of trying to search and replace "\u00dcT:"
