I agree with you but how can I use the raw strings when I want to compose a
text (2nd question)
I tried:
label='$\textrm{test}_2$
xlabel(r label)
xlabel(r+label)
etc but it not working (like I expected). So I would like to know if there are
a way to precise that the text is a raw string by another thing that the r
character just before the string. Perhaps that will be good to have an option
like raw=true or something similar?
Thanks,
N.
