当我想使用python reportlab保存pdf时，使用带有非ASCII字符的路径时会遇到麻烦吗？

Question

我写了一些简单的函数来从reportlab生成pdf，但是当路径为非ASCII（例如中文）时，会出现UnicodeDecodeError: 'utf8' codec can't decode byte 0xd0 in position 3: invalid continuation byte问题UnicodeDecodeError: 'utf8' codec can't decode byte 0xd0 in position 3: invalid continuation byte 。 当路径全为ASCII时，一切都很好。

我的代码非常简单，就像

from reportlab.lib.pagesizes import letter, A4, landscape  
from reportlab.platypus import SimpleDocTemplate, Image  
from reportlab.lib.units import inch  
from reportlab.pdfgen import canvas
from reportlab import rl_settings
import reportlab.lib.pagesizes

filename_pdf = path + path.split('/')[-2]+'.pdf'
c = canvas.Canvas(filename_pdf, pagesize=maxsize )
#some code
c.save()

Answer 1

filename_pdf = filename_pdf.decode('gbk','ignore')
