While studying Django, I had an error where the technical_500.html page
was not properly printed.
[[Image(https://2.bp.blogspot.com/-JFSh6RRcMbs/XKUCH5KmcMI/AAAAAAAA8TU/ZC-
b4fJJNL0auiAtl2fDSMfBf3nAudhtACEwYBhgL/s1600/unicode%2Berror.png)]]
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?

Comment:
The issue here is that reading the various debug templates was changed in
[https://github.com/django/django/commit/ea542a9c7239b5b665797b7c809f1aceb0b412cf
ea542a9] to bypass the template loaders. The template loaders use the
encoding specified on the template engine which is utf-8 by default. Later
in
[https://github.com/django/django/commit/50b8493581fea3d7137dd8db33bac7008868d23a
50b8493] an ellipsis was added and this caused things to blow up on
Windows as `locale.getpreferredencoding(False)` is not utf-8.
Here is an alternative [https://github.com/django/django/pull/11170 PR]
that adds tests and a release note for 2.2.1 as this is a regression.

On line 239, there is a special characters "…", or you can replace it with
"..."
