Every time I update my forum and have to rebuild the sphinx.conf I find myself into the problem of recognising Greek characters.
The solution i have found is adding 2 lines [1] in the conf accoring to a char maps index [unicode-maps.txt] found by googling.

I attach you the sphinx.conf my forum produces and the patched version.

Please include it to your script so we dont edit by hand every time.

We cannot include this in IPB, else the sphinx configuration file would be broken for everyone else NOT using Greek, which is, I'm afraid, the majority of our client base.
