Hello everyone
I’m trying to make a graph in which I want to include text. I want that text to have the character PI (π) and some of a plot like these: ▒
The problem is that when I run it it does not recognize those characters.
How can I solve that?
I support myself. I just saw in searches how they solve it this way:
ascipi = u’π’
text (ascipi, 100, 100)
I wonder if your search ended up here: 
Yes!
There I found the solution. They explain it quite well. I don’t know if there are other methods but that one worked for me.
