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 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.

Abstract translation: 本发明接收到存储具有以第一文本编码编写的文件的文件的请求，将文件名转换为Unicode文件名，并将Unicode文件名和文件存储到存储器中。 然后，本发明设置与存储器相关联的标志，指示已经使用第一文本编码。 要检索Unicode文件名，本发明接收到从内存中查找Unicode文件名的请求。 接下来，本发明使用预定的文本编码将文件名转换为Unicode。 然后，本发明在存储器中搜索Unicode文件名。 如果未找到Unicode文件名，本发明使用已经使用的一组文本编码中的下一个文本编码，重复转换并搜索内存，直到识别出Unicode文件名。 最后，检索Unicode文件。
