There are over 5000 Chinese Characters. Do you think you could fit them all on a keyboard? All Chinese characters have a phonetic equivalent in roman letters. Chinese people use a QWERTY keyboard to type the words phonetically, and then the computer makes the characters for them. Hit the give up button to see all of the names spelled out phonetically.
You can do the pinyin, even with no tone marks. Like if you type in he lan, you get the netherlands as that is the pinyin. I know this is seven years after the question.
