commit 0afc0a7841889c6221fd47430e72f4fe570833f4
Author: Alvaro Herrera <alvherre@alvh.no-ip.org>
Date: Tue Sep 10 20:56:11 2019 +0000
First released in: 13.0
Fix unaccent generation script in Windows
As originally coded, the script would fail on Windows 10 and Python 3
because stdout would not be switched to UTF-8 only for Python 2. This
patch makes that apply to both versions.
Also add python 2 compatibility markers so that we know what to remove
once we drop support for that. Also use a "with" clause to ensure file
descriptor is closed promptly.
