Great idea, and we will support this in the distant future.

I’m marking this as “declined” for now because implementing uni-code symbols, icons, asian-language characters, etc. within our Flash charts would require much larger file sizes and longer load times.

However, in the future we plan on moving away from Flash based charts to HTML 5. The development team has a few other items to work on before getting to that project; however, I would imagine you’ll begin seeing HTML 5 charts sometime this year. This type of format will allow us to support symbols and such easier as well!

Thanks again for your suggestions!
