Hello there.

Thanks to icouto for the excellent post explaining how to move the whole shop to UTF8

I managed to do it thanks to that guide, then it is my turn to give something back to the community,..
Get the file from darthnet40.com/zencart1.3.7-UTF8.zip

This file is ONLY FOR A NEW INSTALLATION (It creates the correct UTF8 Collation and character sets in the new tables).

[U]To use it, follow the steps:
1) Copy the whole Zencart distribution on your server
2) Put the files i provide on your server, overwriting the default ZC ones
3) Run setup as usual
4) Enjoy
