Description:The Kindle Edition of Naughton's Czech, an Essential Grammar is useless. Despite multiple downloads and discussions with Kindle customer service, the book downloads to the Kindle without many accents and diacritical marks on the letters -- for example, throughout the entire book, "R" with hook/hacek -- has no hacek. Same for "r" -- no hook/hacek. The same holds true for other letters with hooks/haceks. Thus, THE BOOK IS USELESS IN ITS CURRENT FORMAT. Without the accents and hooks/hacky, one cannot learn the language. I speak Czech and can see that all the accents are missing, but a non-speaker or learner of the Czech language would not know this, and thus would learn many, many words completely incorrectly. THE PUBLISHERS NEED TO CORRECT THE KINDLE VERSION OF THIS BOOK.
