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.
