讓 pycairo 可以正常顯示中文的賤招，需要利用 wxPython

pycairo_chinese.py

import subprocess

import cairo
import wx
import wx.lib.wxcairo

WIDTH = 400
HEIGHT = 300

surface = cairo.ImageSurface(
    cairo.FORMAT_RGB24,
    WIDTH,
    HEIGHT
)
ctx = cairo.Context(surface)
ctx.rectangle(0, 0, WIDTH, HEIGHT)
ctx.set_source_rgb(0.8, 0.8, 1)
ctx.fill()

# Drawing code
app = wx.App()
wfont = wx.Font(
    13,
    wx.FONTFAMILY_DEFAULT,
    wx.FONTSTYLE_NORMAL,
    wx.FONTWEIGHT_NORMAL,
    False,
    '蘋果儷細宋'
)
cfont = wx.lib.wxcairo.FontFaceFromFont(wfont)
ctx.set_font_face(cfont)
ctx.set_font_size(13)
ctx.set_source_rgb(0, 0, 0)
ctx.move_to(20, 80)
ctx.show_text('Your grand mom, 你啊罵勒')
# End of drawing code

surface.write_to_png('text.png')
subprocess.run(['open', 'text.png'])
