18091	Non-ASCII templates break `django-admin.py startproject --template=TEMPLATE`	Antti Kaihola	nobody	"If a file in a project template for `manage.py startproject --template=TEMPLATE`
* has non-ASCII characters in its contents, and
* is named with one of the extensions given in the `--extension=` argument,
a !UnicodeDecodeError is raised:

}}}

The content of the template file is read from the disk as a bytestring (line 156) and run through the Django template engine, which outputs the rendered text as a Unicode object (line 159). The Unicode object is then attempted to be written in to a file without encoding it first (line 161).

Files whose extension '''isn't''' included in `--extension=` are read from the disk, '''not''' run through the template engine and written back to the destination without any decoding or encoding. For this reason, those files are handled without problems even if they have non-ASCII content."
