The BIG problem with books is that most of the books printed today are in english...................if you look at the number of countries where english is one of the main languages, there are PLENTY of books in english................I was in Germany recently.............and there were very FEW books in german...........why? Because nowadays German is just a minority language............even if german is spoken in MANY european countries............Italy is even worse............when most italians say that they are reading a book.........it is usually a cartoon comic about "Dylan Dog" or somesuch cartoon character......................!!!
In my opinion, the thai government should organise an "approved" transliteration of the thai language, and use Roman characters.............to print literature for thais.......in the same way this was done many years ago in Turkey.............!
Sorry for boring you.........
