Abstract
The invention receives a request to store a file having a filename written in a first text encoding, converts the filename into a Unicode filename and stores the Unicode filename and the file into memory. The invention then sets a flag, associated with the memory, indicating that a first test encoding has been used. To retrieve a Unicode filename, the invention receives a request to locate a Unicode filename from memory. Next, the invention uses a predetermined text encoding to convert the filename in to Unicode. The invention then searches for the Unicode filename in the memory. If the Unicode filename is not found, the invention uses a next text encoding from the set of text encodings which have been used, to repeat the conversion and searches the memory until the Unicode filename is identified. Lastly, the Unicode file is retrieved.
