• Alternate option using Pandas
• Specify a TrueType font and then set the FontProperties.
  • A font may be specified using the absolute path to a font file, by using the fname kwarg. However, in this case, it is typically simpler to just pass the path (as a pathlib.Path, not a str) to the font kwarg of the Text object.
• Basically, in order to display a particular type of font as the figure tick labels, matplotlib must be configured to use the correct font type.
  • How I got Matplotlib to plot Apple Color Emojis suggests setting a matplotlib backend that supports TrueType collections (ttc).
• Using data from the OP
• Interestingly, if you look at the column names of df, the Hindi characters and emojis display correctly.
• Also, if you look at the list text, all the characters are properly displayed.
• I can't get the emojis to properly display on the plot figure.

import pandas as pd
import matplotlib.pyplot as plt
from pathlib import Path
from matplotlib.font_manager import FontProperties

# point to the font location with an absolute path
nirm = Path('c:/Windows/Fonts/Nirmala.ttf')

# configure the Hindi font
hindi_font = FontProperties(fname=nirm)

# create the dataframe
df = pd.DataFrame(data, index=['Views', 'Likes', 'Dislikes', 'Comments'])

# pandas.DataFrame.plot uses the index for the axis so Transpose df and then plot
ax = df.T.plot.barh(stacked=True, figsize=(10, 14))

# get the y tick labels
text = [item.get_text() for item in ax.get_yticklabels()]

# set the labels with the ttf
ax.set_yticklabels(text, fontproperties=hindi_font)

# annotate the bars
for rect in ax.patches:
    # Find where everything is located
    height = rect.get_height()
    width = rect.get_width()
    x = rect.get_x()
    y = rect.get_y()

    # The width of the bar is the count value and can used as the label
    label_text = f'{width:.02f}'

    label_x = x + width / 2
    label_y = y + height / 2

    # don't include label if it's equivalently 0
    if width > 0.001:
        ax.text(label_x, label_y, label_text, ha='center', va='center', fontsize=8)

plt.show()

Render Hindi characters as follows: First run the Linux command fc-list :lang=hi family (see https://linux.die.net/man/1/fc-list) to generate the complete list of Hindi fonts, and from there select Arial Unicode MS.

Add this to the matplotlib font parameter, together with 2 others:

mpl.rcParams['font.sans-serif'] = ['Source Han Sans TW',
                                   'sans-serif',
                                   'Arial Unicode MS'  # fc-list :lang=hi family
                                   ]

Next, translate emojis to text with the emojis package which can be installed from pypi (use command: pip install emojis):

import emojis

labels = list(data.keys())
labels_decoded = [emojis.decode(label) for label in labels]

This produces text description of emojis instead of their graphical representations (e.g. :airplane:). For a graphical representation, you could try using https://github.com/matplotlib/mplcairo

Complete program:

import numpy as np
import matplotlib.pyplot as plt
import matplotlib as mpl
