This worked great! in Osclass 3.8.
For the Greeks you should copy this is functions.php of your theme:
<?php
function cust_cyrillic_to_latin($textcyr) {
$cyr = array('α','β','γ','δ','ε','ζ','η','θ','ι','κ','λ','μ','ν','ξ','ο','п','ρ','σ','τ','υ',
'φ','χ','ψ','ω','Α','Β','Γ','Δ','Ε','Ζ','Η','Θ','Ι','Κ','Λ','Μ','Ν','Ξ','Ο','Π','Ρ','Σ','Τ','Υ',
'Φ','Χ','Ψ','Ω','ί','ό','ώ','ά','ή','έ','€');
$lat = array( 'a','b','g','d','e','z','i','th','i','k','l','m','n','x','o','p','r','s','t','y',
'f' ,'x' ,'ps' ,'w','A','B','G','D','E','Z','I',
'TH','I','K','L','M','N','X','O','P','R','S','T','Y',
'F' ,'X' ,'Ps' ,'W' ,'i' ,'ο' ,'w', 'a', 'h', 'e', 'euro');
return str_replace($cyr, $lat, $textcyr);
}
?>
Can anyone help how do the same with Categories?
