Google's transliteration software is good enough to translate your Hindi written in English alphabets. I have to write "फॉण्ट साइज़ कुछ ज्यादा ही छोटा नही है?" using my English keyboard. I have visited Google's transliteration link and typed "font size kuch jyada hi chota nahi hai?" If you just copy this Hindi in English then Google transliteration will not work. But when you type then as soon as you complete a word and press 'space' key google's software will translate your word.
