Hello Chris.
Thanks for your interest.

Absolutely.

Presumably you expect to run this from the command line. It works as
expected:

French: année
3.5.3 (default, Sep 27 2018, 17:25:39)
[GCC 6.3.0 20170516]

However, with a slight modification:

#!/usr/bin/env python3

import sys
from jinja2 import Template
print ("Content-type: text/html\n\n")
print(Template("French: {{french}}").render({"french": "année"}))
print(sys.version)

and running it in a browser (tried both chrome and Firefox),
it fails as before: blank web page. Replacing the accented character
displays the expected result:

French: annee 3.5.3 (default, Sep 27 2018, 17:25:39) [GCC 6.3.0 20170516]

Thanks to all who have pitched in. As I previously mentioned, I have a
work-around, so no big deal, but I would like to get to the bottom of this.

Cheers, Tony
