Hi guys, Would you be interested in adding a utility class that creates alphabet converters, perhaps using a helper method available from StringUtils? It doesn't have to stay the way it is now, but the API for the class - AlphabetConverter - is currently: /** * The input is integers representing code points, but we can make it accept chars as well * * doNotEncode represents chars we want to leave in the original state (not to encode them using the chars in encoding) */ public AlphabetConverter(Set<Integer> original, Set<Integer> encoding, Set<Integer> doNotEncode); public String encode (String original);
public String decode (String encoded); In StringUtils, we could add public AlphabetConverter getAlphabetConverter (Set<Integer> original, Set<Integer> encoding, Set<Integer> doNotEncode); I used it to convert from unicode to latin letters, without using any chars I wanted as delimiters, and preserving the English alphabet as is for readability. If you'd like to add it, I'll clean up the code and prepare it for a pull request so you can review it. It makes sense to me to add a method that returns the HashMaps used internally for the mappings so they can be serialized (and deserialized) for preserving the mapping. Regards,Eyal Allweil (PayPal)
