The Latin alphabet is the most widely used. But there are billions of other people who use either Chinese characters, Brahmi/Abugida scripts, Cyrillic or Arabic.  

To deal with addresses in a different script to Latin, most address verification solutions cover a variety of scripts such as Cyrillic, Greek, Hebrew, Kanji (Japanese), Chinese, Arabic, Thai and Hangul (South Korea). This gives your end user the choice to enter their address and see the verified search results come back in their native language, which is great for the user experience.
