how to use the delta character (Δ) in a graph

[Fred Chuit]

Hi ejs-users,

I would like a Graph with the delta sign (Δ) in title and axes.
When I fill in the plotting panel:
Title: ΔT,Q
Title Y: ΔT (°C)
It looks good in the edit screen.
When I run the applet the Δ character changes into ? character.
Who knows how to fix this?

Already thanks for your help and advice.
Regards,
Fred

I copy and paste those characters directly into string property for title and Yaxis.
And it seems work find when I view it and run it as application.
Please check out the follwoing applet. (Did you see the same title/ytitle?)
Title: ΔT,Q
Title Y: ΔT (°C)
