wp/tests/phpunit/data/formatting/utf-8

The Python scripts are for generating test data, because Python's Unicode
support is much, much, much, much better than PHP's.

* `utf-8/urlencode.py`, `utf-8/u-urlencode.py` and `utf-8/entitize.py` process UTF-8
into a few different formats (%-encoding, %u-encoding, &#decimal;)
and are used like normal UNIXy pipes.

Try:

`python urlencode.py < utf-8.txt > urlencoded.txt`
`python u-urlencode.py < utf-8.txt > u-urlencoded.txt`
`python entitize.py < utf-8.txt > entitized.txt`

* `windows-1252.py` converts Windows-only smart-quotes and things
into their unicode &#decimal reference; equivalents.
