Excellent idea
Well it's not really my language, but my adopted language has 28 or 29 letters, it adds three extra letters to the standard Roman "English" alphabet - æ ø å. In a dictionary the come in that order after -z-. The reason that it's uncertain whether there are 28 or 29 letters in the alphabet - according to my Danish teacher - is that there are no Danish words with -w- so although you will see -w- written in Denmark all the words featuring a -w- are imported words. So Danish itself doesn't have a -w- therefore, the argument goes -w- is not part of the Danish alphabet.
You think that's complicated, you want to try pronouncing it!
