Pathauto is the most common module which i think almost all Drupal websites use it to format the path alias. Sometime we want to use the node title as part of the path alias but if we are working on multilingual Drupal website, this may lead to non english URL.
So we have the Transliteration module to solve the problem. It takes Unicode text and tries to represent it in US-ASCII characters by attempting to transliterate the pronunciation expressed by the text in some other writing system to Roman letters. In addition, it also helps creating clean file name on file upload.
1. Download and install the Transliteration module.
2. Go to URL aliases setting page. (admin/config/search/path/settings)
4. Create a node with non-english title and check the Generate automatic URL alias checkbox.
