• This and this on stack exchange

Here I used sinhala as Indic Script instance.
I think the font family has to do something with this issue since output to different font families are different. I'm not an expert in these stuff. Help appreciated to to get this work even with a different font family.
An example is given below for which I've tried with 3 different font families.
Code for reproduction

from matplotlib import rc
families = ['WARNA','LKLUG','Arial']
for familyname in families:
    rc('font', family=familyname)
    from matplotlib import pyplot as plt
    import numpy as np
    r = np.linspace(0.1,5,100)
    A = 3*2/(r*2)+np.pi*r**2
    fig = plt.figure()
    axes = fig.add_axes([.1,.1,.8,.8]) 
    axes.plot(r,A)
    axes.set_ylabel(u'වර්ගඵලය')
    axes.set_xlabel(u'අරය')
    axes.set_title(familyname)

Actual outcome

Expected outcome

Result 1 looks fine but it has 2 problems:

• Accents not been placed in the correct location. ("්" in "වර්ගඵලය" is placed after "ර" not before)
• Letter "A" is not renderd in the title "WARNA"

Issues in result 2:

• Same previous accent issue
• Axis values or title not shown at all

Issues in result 3:

• No Sinhala script shown.
