Non-latin characters transformation in the SEO-friendly URIs
The SEO-friendly URL generation function removes non-latin letters. But
some of them are important letters that should be transformed to their
closest-match latin characters in the URIs. Google sees these special
letters as synonyms to visually almost identical latin symbols. But
removing them destroys words and makes the URL SEO effort pointless.
This requires a simple PHP transform function, so that all these symbols
are transformed to corresponding latin letters. I see "Å¡" is
transformed already, so probably you need only to include other
characters in the function array as well.
