This is mostly encountered with pathlib in python 3, but this API
suggests any PathLike object can be treated like a filepath with
`__fspath__` function.
We've discovered that passing Unicode in Host actually works, except for
test client limitations on Python 2 - and the only things that don't
work are non-printable characters.
If create_url_adapter raises (which it can if werkzeug cannot bind
environment, for example on non-ASCII Host header), we handle it as
other routing exceptions rather than raising through.

Flask currently supports importing app through a combination of module
path and app variable name, such as '/usr/app.py:my_app'. When the
module path contains a colon, it will conflict with this import way and
a `flask.cli.NoAppException` will be raised.
A file path on a Windows system may contain a colon followed by a slash.
So we solved this problem on Windows by ignoring the colon followed by a
slash when we split app_import_path.
Fix issue #2961.
1.Grammar error: 'return' should be 'returns'; 'would is' should be
'would be'.
2.Reloader is used to reload and fork process if modules were changed
rather than when an exception occurred.
3.The sample code is not concise enough.
http://flask.pocoo.org/docs/1.0/quickstart/#url-building
In the URL Building section of the quickstart, the script output is shown right after the code.
This breaks syntax highlighting for the whole code-block. To fix this, I have made the output into comments.
Otherwise the example fails with the following error:
"name = name or cmd.name AttributeError: 'function' object has no attribute 'name'".
