Hi Jimmy, Thank you for your replies.
Shouting - so that people find it easy to locate the actual questions. < Well, that's what 'DangAmbigs' are for -- impossible sequences, and their corrections. > >From my understanding of DangAmbigs, I did NOT infer that it could be used for impossible sequences. As in English no sequence is impossible (bam and barn are both valid right). But with Unicode characters, a lot of sequences are impossible. Eg:- A vowel symbol with out a consonant preceeding it. Invalid sequence of combining characters etc. ( http://en.wikipedia.org/wiki/Combining_character ) "WHY NON DICTIONARY based solutions?" 1) That is because in English, you have 'dry' words. If you are familiar with German you will know that words can be joined. like 'autobahn'. This is taken to the limit in Indian languages. 2) In agglutinative languages like Telugu, the phrase 'from in between them' could be just the word వాఱిరువురిమధ్యలోనుండి। Hence there is no limit to the number of words that a dictionary should have. 3) In English, a word, say 'fast' is pronounced differently in different countries, but written the same. But in Telugu etc. 'poyaadu' in another accent becomes 'poyindu'. 4) There are Sandhis that alter a word's spelling based on the next or previous words. http://en.wikipedia.org/wiki/Sandhi The above reasons make building a comprehensive dictionary impossible. Hence making provisions for them in the code seemed like a smarter, though harder, thing.
