   A work around for at least rendering the text is as follows

   from fontTools.ttLib import TTFont
   import matplotlib.font_manager as mfm
   import matplotlib.pyplot as plt
   
   def char_in_font(Unicode_char, font):
       for cmap in font['cmap'].tables:
           if cmap.isUnicode():
               if ord(Unicode_char) in cmap.cmap:
                   return True
       return False
   
   def label_unicode(char, axs,x=0.5,y=0.5):
       
   
       font_info = [(f.fname, f.name) for f in mfm.fontManager.ttflist]
       
       print('finding fonts for ',char)
       font_list = []
       for i, font in enumerate(font_info):
           if char_in_font(char[1], TTFont(font[0], fontNumber=0)):
               #print(font[0], font[1]) #uncomment to see all your fonts
               font_list.append(font[0])
               
       font_path = font_list[-1]
       prop = mfm.FontProperties(fname=font_path) # find this font
       axs.text(x, y, s=char, fontproperties=prop, fontsize=20)
   
   f, axs = plt.subplots()
   plt.plot([i for i in range(5)])
   label_unicode(u"#방탄소년단 ",axs,1,1)
   label_unicode(u"#裏垢女子",axs,1.5,2)
   label_unicode(u"#🔥",axs,2,3)
   plt.show()

   allowing lists of fonts to be specified for each handle label, rather than enforcing using one font.

   The problem is well understood, but would require major rearchitecting of the text handling machinery, so is unlikely to happen soon.

   I'll close this in favor of #18883 which is essentially the same but points more explicitly at font-family fallbacks.
