My drupal version is : 7.5x
I want to import an csv or txt file that have non-unicode (iransystem) encoding.
After import this file to Drupal (persian character with iransystem encoding) my characters show correctly in my site. So these texts are imported successfully. But when I want to filter results of those fields by Views (exposed filter), I can not see any result by filtering views fields (search in fields by views exposed filter).
I want to import non-utf8 or unicode persian text files into Drupal and filter those fields by Views exposed filter (search on non-unicode characters).
For example I imported
A Persian or arabian word into a field of Drupal. This passage shows correctly to me, but when I search type this passage in exposed
A Persian or arabian word text in Drupal page and paste on search field of Drupal Views, I can see results correctly.
