I’m making the assumption that you are sorting by English collation rules and have alphabetic text. The code below is a good start, but the real world is more complicated than that. (For example, Chinese text has different lexicographic rules depending on the context, e.g. general-purpose dictionary, karaoke song lists, electronic door bell name list, .) I cannot present a perfect solution because the question had so little information.<\/p>\n
