How to write markers in a text?

Hello, everyone. could tell me how to write a marker into a text?
I see some letters(for example: α) or mathematical symbol (for example:/)can be wrote as #alpha and #/. But I don’t know how to record these markers (for example:◆◇○★■△▲) into a text.
Thank you for your suggestion and advice.

You cannot include objects like markers, lines in a TText/TLatex.
Just in case, you simply want to write a legend, see class TLegend and many examples in the tutorials, eg $ROOTSYS/tutorials/fit/FittingDemo.C


Following your instuctions, I found the way finally.Thank you.
