UniCodeError in Heat software config hooks in case of special characters

[Thomas Spatzier]

When working with Heat software config and the script hook, I got the following error when writing the 'config' script to a file:

UnicodeEncodeError: 'ascii' codec can't encode character u'\u2019' in position 620: ordinal not in range(128)

The error is raised here:

https://github.com/openstack/heat-templates/blob/master/hot/software-config/elements/heat-config-script/install.d/hook-script.py#L58

Seems to be caused by a special character in the script.
I guess the same error also exists for the other software config hooks.

    Use utf-8 encoding when writing config scripts

    Change from default encoding 'ascii' to 'utf-8' encoding when writing
    config scripts (stored in Heat software config's 'config' attribute).
    The default ascii encoding causes issues when config scripts include
    special characters.
