Abstract: Methods, a data structure and computer readable mediums address newly-defined code points in a Unicode index of characters by allowing processing of strings that use those newly-defined code points although a database holding an index of Unicode characters has not yet been updated. A method is directed to processing strings including one or more code points associated with an index of code points mapped to an expandable alphabet, such as the Unicode index. The method includes tracking each string that has code points mapped to undefined items and processing the tracked strings outside the processing of strings with defined items. An embodiment provides for creating a database for maintaining the index to the code points mapped to the previously undefined items. For each code point mapped to a previously undefined item a table entry can be created so the entries identify newly defined code points to enable processing the tracked strings.
