It looks like some basic unicode charecters are supported in Thinkscript but not supported in the chart label. For example, unicode¼ (U+00BC ) shows properly in the AddLabel thinkscript code and it also shows properly on the actual chart label. However, U+2193showes properly in the AddLabel thinkscript code but displays as and unknown character  on the chart label. How can i get a list of supported Unicode charectors that THinkorSwim supports in labels? Does anyone have any insight into this?
