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 text 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 into 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.
