Add UTF-8 encoding header to Python scripts. (rebase)

[mtbc]

rebases #904

[snoopycrimecop]

Conflicting PR. Removed from build OMERO-merge-develop#201. See the console output for more details.

[mtbc]

I'll wait for #941 to close, then try again.

[mtbc]

Okay, try including again?

[joshmoore]

Label removed.

[manics]

Good to merge.

The only remaining files are sphinx/conf.py in the submodules, and files in bioformats/components/xsd-fu

$ cat tmp.sh
#!/bin/sh
if [ ! -s "$1" ]; then
        exit 0
fi

if [ "$(head -n1 $1 |sed -e 's/[[:space:]]*$//')" != '#!/usr/bin/env python' ];
then
        echo "Incorrect #! line: $1"
fi

head -n2 "$1" |grep '^# -\*- coding: utf-8 -\*-' > /dev/null
if [ $? -ne 0 ]; then
        echo "Incorrect coding line: $1"
fi

$ find . -iname \*.py -exec ./tmp.sh {} \; |grep -v ./components/bioformats/components/xsd-fu
Incorrect #! line: ./components/bioformats/docs/sphinx/conf.py
Incorrect #! line: ./docs/sphinx/conf.py

Thanks! Hmm, I wonder if there's some generator of Python code that should be tweaked.

[joshmoore]

conf.py is generated by sphinx, so outside our realm.

[mtbc]

Is it a one-off generation or does it get regenerated sometimes? If the latter, ome/omero-documentation#303 may be a waste of time.

[joshmoore]

One-off.

[mtbc]

Hmm. Maybe we can adopt the ome-documentation one then. (-:
