Application ID: 11360797

Base Claim:
1. A computer-implemented method for storing filenames in a memory device, comprising: setting a default text encoding to be the same as a text encoding that is used to display text on a monitor coupled to the memory device; receiving a first user input, the first user input being a filename, the filename presented on the monitor in the form of the default text encoding; converting the filename from the default text encoding to Unicode text encoding to form a converted filename; storing the converted filename in the memory device; modifying an encoding bitmap to indicate the use of the default text encoding, wherein the encoding bitmap includes a list of text encodings for different languages; receiving a second user input, the second user input being the filename, the second user input for a file retrieval request, the filename again presented on the monitor in the form of the default text encoding; converting the filename of the second user input from the default text encoding to Unicode text encoding to form a second converted filename; and, retrieving the file from the memory device by identifying a match between the converted filename and the second converted filename.

Claim 2:
2. The computer-implemented method of claim 1 wherein the encoding bitmap indicates those of the text encodings that have been previously used.
