python - 如何修复 Django Translation ASCII 解码错误？

Question

我有这个 django 网站从 locale/lc_messages/django.po 和 django.mo 文件将英语翻译成德语。但是，当我尝试翻译德语字母如 ü 和 ä 时，它给了我错误

'ascii' codec can't decode byte 0xc3 in position 7: ordinal not in range(128)

据我所知，django 正试图通过 ASCII 解码 unicode 字符，这是不可能的。但我该如何解决这个问题？我应该在哪里设置 django 通过 utf-8 解码而不是通过 ASCII 解码。如果我错了，请告诉我。

Unicode error hint

The string that could not be encoded/decoded was: ne pr��fung

这是我来自 django.po 的 msgid 和 msgstr

#: .\app\templates\app\layout.html:47
msgid "Take Exam"
msgstr "Eine prüfung anlegen"

Answer 1

找到解决方案，必须将所有 .po 文件中的 header 放在顶部。

"MIME-Version: 1.0\n"
"Content-Type: text/plain; charset=UTF-8\n"
"Content-Transfer-Encoding: 8bit\n"
"Plural-Forms: nplurals=2; plural=(n != 1);\n"

感谢大家的帮助。使用 poedit 处理 .po 文件是更好的解决方案
