encoding - 如何使用 python-docx 将具有非 UTF 字符的 JPEG 图像添加到 docx 中？

Question

我正在尝试使用 python-docx 将一系列 JPEG 插入 Word 文档，但似乎其中一些可能包含非 UTF-8 元数据，这导致 docx 发出 Unicode 解码错误消息。我怎样才能解决这个问题？

这是代码：

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

from docx import Document
from docx.shared import Inches
from docx.enum.table import *
from docx.enum.text import WD_ALIGN_PARAGRAPH
from PIL import Image
from PIL.ExifTags import TAGS

document = Document()


table = document.add_table(rows=1, cols=1)
table.alignment = WD_TABLE_ALIGNMENT.CENTER
row_cells = table.add_row().cells
paragraph = row_cells[0].paragraphs[0]
paragraph.alignment = WD_ALIGN_PARAGRAPH.CENTER
run = paragraph.add_run()


run.add_picture("143269.jpg", height=Inches(5))
document.save('demo.docx')

和错误回溯

和一个示例问题 jpeg。

大多数jpgs工作。
