30324	UnicodeDecodeError when loading debug templates.	chihun-jang	Nick Pope	"While studying Django, I had an error where the technical_500.html page was not properly printed.

In the log window, UnicodeDecodeError was continuously printed, and in the template, the sentence 'A server error occured. Please contact the administrator' was printed



So when I checked the technical_500.html file of Django 2.2version, I found that the dotdotdot wrapped by the <span>tag on the 239th line was changed to ellipsis.

Apparently, the version of Django 2.1.8 was a dotdotdot.

So I took steps to change the 239th line's ellipsis to dotdotdot.

Or, when reading the technical_500.html file from inside the debug.py file, the encoding format was set to utf-8.

This enabled me to resolve the error.

Did you intentionally modify the technical_html file?
