The following program fails with:
---
X Error of failed request: BadLength (poly request too large or internal Xlib
length error)
Major opcode of failed request: 138 (RENDER)
Minor opcode of failed request: 20 (RenderAddGlyphs)
Serial number of failed request: 4248
Current serial number in output stream: 4956

Python program:
---
from tkinter import Tk
from tkinter.scrolledtext import ScrolledText
root = Tk()
text = ScrolledText(root, width=80, height=40)
text.pack()
for i in range(0x10000, 0x40000, 32):
chars = ''.join(chr(i+j) for j in range(32))
text.insert('insert', f"{hex(i)} {chars}\n")
input("Press enter to exit")

It seems like the first character which triggers this RenderAddGlyphs BadLength
issue is: U+1f6c2. See attached emoji.png screenshot. As you can see, some
emojis are rendered in color in Gnome Terminal. I guess that it uses the Gtk 3
pango library to render these characters.
