oh. They showed up in some basic example code for pyglet:
import pyglet
window = pyglet.window.Window()
label = pyglet.text.Label('Hello, world',
font_name='Times New Roman',
font_size=36,
x=window.width//2, y=window.height//2,
anchor_x='center', anchor_y='center')
@window.event
def on_draw():
window.clear()
label.draw()
pyglet.app.run()

writing a few small ones with various prints to see what happens.
